<h2 style="text-decoration: underline;">How would I report a bug?</h2>
<p>
Use the <a href="http://www.tufat.com/forum/forumdisplay.php?f=59">support forum</a> of tufat.com.
</p>
<p> 
Please, provide the following:
<ul>
<li><code>phpinfo()</code> output;</li>
<li>script version (and information about applied patches, if any);</li>
<li>script parameters you're using for conversion;</li>
<li><b>full</b> HTML code of the page you're trying to convert.</li>
</ul>
The will greatly reduce the time required for solving your issue. Thank you for understanding.
</p>
</div>

<h2 id="installation">Installation.</h2>
<dl>
<dt id="installation-utilities">Does html2ps require any external utilities like ghostscript?</dt>
<dd>No. PHP with GD extension is sufficient to run conversion. You <em>may</em> use additional 
extensions/utilities to use alternative output methods or to boost conversion speed a little bit, though.</dd>
<dt id="installation-commandline">Can I call this script from the command line?</dt>
<dd>Probably yes; check if your PHP support command line interface. Also, consider 
reading this article on php.net: 
<a title="Click to open article in new window" href="http://www.php.net/manual/en/features.commandline.php" target="_blank">
Using PHP from the command line</a> 
</dd>
<dt id="installation-version">How can I determine the script version?</dt>
<dd>Look in config.inc.php for HTML2PS_VERSION_MAJOR, HTML2PS_VERSION_MINOR and HTML2PS_SUBVERSION constants. The full version number is
 MAJOR.MINOR.SUBVERSION. If you cannot find these constants, you're using <em>very old</em> html2ps release.</dd>
</dl>

<h2 id="nooutput">No output at all. Broken output.</h2>
<dl>
<dt id="nooutput-regexp">I'm getting "Warning: DOMDocument::loadXML() [function.DOMDocument-loadXML]: Empty string supplied as input" error message in PHP 5.2.0 when attemting to convert some files</dt>
<dd>A new configuration parameter <tt>pcre.backtrack_limit</tt> was introduced in PHP 5.2.0. html2ps does the excessive
regexp usage; it is recommended to increase pcre.backtrack_limit value to 1000000. 
</dd>

<dt id="nooutput-utf8">Warning: DOMDocument::loadXML() [function.DOMDocument-loadXML]: Input is not proper UTF-8, indicate encoding ....</dt>
<dd>The page you're trying to convert specifies UTF8 encoding in header / meta tag, but is face uses different encoding. You need 
to switch from "Autodetect" encoding to the real one (in most cases iso-8859-1 will do) if you want to convert such page.</dd>

<dt id="nooutput-php442">HTML2PS returns blank page. There's some strange messages in PHP error log, for example:
<pre>
Parent: child process exited with status 3221225477 -- Restarting.
</pre>
I'm using PHP 4.4.2 </dt>
<dd>It is a PHP 4.4.2 bug <a href="http://bugs.php.net/bug.php?id=36017">#36017</a>; there's no workarounds 
except changing PHP version or writing your own fetcher without 'fopen' function calls. 
I would recommend either downgrading to earlier 4.4.x versions or installing PHP 5.
</dd>

<dt id="nooutput-memory">All I'm getting is a blank page; no error messages in PHP error log. Whats happened?</dt>
<dd>
The script is probably running out of memory or execution time. Try increasing 
the values of <code>max_execution_time</code> and/or <code>memory_limit</code> PHP configuration variables. 
Recommended values are <strong>120</strong> seconds and <strong>32</strong> megabytes. Nevertheless, if you're 
using <em>VERY</em> big images, you'll probably need to increase these values 
even more.
</dd>
<dd>
Another cause may be a JavaScript or META redirect on page you're trying to convert. As HTML2PS script is not designed 
as interactive user agent, it will not follow such redirects for you. You may try to open the url in question in your browser
and check if the URL will change when page finishes loading. In this case, just supply the final URL to the script.
</dd>
<dd>
Also, please note that domain.com and www.domain.com <em>may</em> point to different sites. In the worst case, 
domain.com (without 'www' part) may just ignore HTTP requests. On the other side, popular browsers try to guess correct
URL; for example, when you enter 'something' to the address bar, they may try to get something.com or www.something.com. 
This may lead to problem similar to one described in previous paragraph; the solution is the same: open URL in browser and
check it will change.
</dd>
<dd>
Yet another cause may be browser built-in timeout; in particular, Safari for Windows has a built-in timeout of 60 seconds. In this case
you will not be able to get the PDF file if conversion takes more than a minute.
</dd>

<dt id="nooutput-memory2">I got the following error message: <tt>Fatal error: Allowed memory size of &hellip; bytes exhausted (tried to allocate &hellip; bytes) in&hellip</tt></dt>
  <dd>The script is running out of memory. Please refer to <a href="php.net/ini.core">memory_limit PHP.net documentation</a> regarding increasing memory limit.</dd>

<dt id="nooutput-php440">The script just hangs when converting page containing images! With &quot;render images&quot; options disabled it works!</dt>
<dd>There were reports on this problem on Windows recently. A quick investigation showed that for some reason PHP 4.4.0
sometimes hangs indefinitely <em>inside</em> the 'fsockopen' call. Consider upgrading your PHP version in this case.</dd>

<dt id="nooutput-limits">I've increased limits, but still sometimes get a blank page immediately 
  after the script starts! Some sites are parsed, though...</dt>
<dd>Some users encountered this problem using the GD library bundled with PHP. 
  While it matched the GD version requirement, it sometimes caused PHP to silently 
  die on some images. The problem is solved by recompiling the PHP using the 
  external (recent enough) GD library. Note that NOT ALL PHP configurations 
  are subject to this problem.</dd>

<dt id="nooutput-firefox">I'm getting &quot;PDF doesn't start with &quot;%PDF-&quot; message from 
  Acrobat Reader. Nevertheless, when I save file to my hard drive, it opens 
  perfectly. I'm using Firefox. 
<dd> There were user reports on issues related to Firefox/Acrobat Reader plugin 
  incompatibility. In particular, this problem appeared with Firefox 1.0.7 and 
  Reader 6.0.2 PL. You may consider upgrading your software to latest versions 
  in this case.</dd>

<dt id="nooutput-cache">Some characters are displayed incorrectly or missing.</dt>
<dd>
<p>If you've installed, removed or changed font files, you may need to clear
<tt>cache</tt> subdirectory. HTML2PS do store information extracted from file fonts
there to reduce script initialization overhead. See also 
&quot;<a href="#fonts-ttf-cache">I've installed/updated True-Type fonts, but it seems that ... (some mysterious problem) ... happens</a>&quot;
<p>Another cause of this problem may be incorrect source encoding; when encoding is not explicilty specified,
html2ps tries to take encoding from HTTP headers and META tags. If no encoding information found, 
html2ps assumes iso-8851-1.
</dd>

<dt id="nooutput-file-protocol">I cannot fetch files from local hard disk using 'file' procolol.</dt>
<dd>
<p>First of all, please ensure you're providing URL, not the file path; for example, if you're trying to use
image from <tt>c:\foo\bar\baz.gif</tt>, you'll need to use the following URL: <tt>file:///C:/foo/bar/baz.gif</tt>.</p>
<p>Second, due the security reasons, files accessed via 'file' protocol are limited to html2ps directory by default. This restriction
is controlled by <tt>FILE_PROTOCOL_RESTRICT</tt> constant in the <tt>config.inc.php</tt> file. Note that this constant 
contains <em>file path prefix</em>; for example, to use files from <tt>C:\images</tt> directory you'll need to 
store <tt>C:\images\</tt> value in this constant.
</dd>
</dl>

<h2><a name="layout-broken"></a>Broken layout.</h2>
<dl>
<dt id="layout-broken-missing-characters">Some characters are missing in my PDFs on some Acrobat Reader versions / different OSes</dt>
<dd>Try enabling font embedding (set 'embed' property in html2ps.config to value 1 for fonts used in your documents).</dd>

<dt id="layout-broken-width">Sites are cut-off on the right side when I'm using 640 pixels page width. What can I do?</dt>
<dd> Nothing. Treat this as a feature. Just increase the page width. Most sites 
  are <b>NOT</b> designed for such small resolutions and will cause a horizontal 
  scrollbar to appear in browser in such cases. </dd>

<dt id="layout-broken-pixelpoint-ratio">I've disabled the &quot;Keep screen pixel/point ratio&quot; option and the 
  page layout is completely broken! What can I do?</dt>
<dd> Nothing. Treat this as a feature. If you want to get the layout close to 
  the image rendered by the browser, <b>never</b> disable this option. The only 
  time you'll need it is when you need to render text having the <b>exact</b> 
  size specified in points.</dd>

<dt id="layout-broken-black-images">Some images are rendered inside black rectangles!</dt>
<dd>PNG images with alpha channel are NOT supported. Swicth to single-color transparency, if you need it.</dd>

<dt id="layout-broken-horizontal-lines">Horizontal lines (e.g. line under the text) look like they consist of several parts with slightly different width.</dt>
<dd>Try disabling antialiasing in your PDF reader.</dd>

<dt id="layout-broken-absolute-positioned">My absolute-positioned content is cut at the last page</dt>
<dd>Note that absolute and fixed-positioned content do not generate page breaks (see CSS 2.1. 13.2.3 Content outside the page box). The simplest 
workaround is to add static-positioned div with fixed height.</dd>

</dl>

<h2><a name="output-customize"></a>Customizing output.</h2>
<dl>
<dt><a name="explicit-break"></a>How can I make an explicit page break?</dt>
<dd>
You may use <em>one</em> of the following HTML2PS script-specific commands:
<pre>
&lt;!--NewPage--&gt;
&lt;pagebreak/&gt;
&lt;?page-break&gt;
</pre>
Or CSS <em>page-break-after</em> property:
<pre>
&lt;div style=&quot;page-break-after: always&quot;&gt;
... some content ...
&lt;/div&gt;
</pre> 
</dd>

<dt><a name="headers-footers">How should I add headers or footers to generated Postscript / PDF files?</a></dt>
<dd>
You may use one of the following options:
<ul>
<li>Use blocks with 'position: fixed'. Pleas note that you probably want to 
set 'top' and 'bottom' properties to negative values to avoid overlapping with
main content; it is an expected behavior according to HTML/CSS standards. 
(see also a simple <a href="samples/headfoot.html">sample</a>)</li>
<li>Use &quot;Header&quot; and &quot;Footer&quot; options in web interface or 
PreTreeFilterHeaderFooter filter in API</li>
<li>Use <a href="compatibility.css.3.html#marginboxes">CSS 3 margin boxes</a>.</li>
</ul>
Note that when you use PreTreeFilterHeaderFooter or Header/Footer fields in web interface,
content is implicitly placed in fixed-positioned div; you may think of this as follows:
<pre>
...
&lt;body&gt;
&lt;!--header starts--&gt;
&lt;div style="position: fixed; ...."&gt;...your header content...&lt;/div&gt;
&lt;!--header ends--&gt;
...
your HTML content
...
&lt;!--footer starts--&gt;
&lt;div style="position: fixed; ...."&gt;...your footer content...&lt;/div&gt;
&lt;!--footer ends--&gt;
&lt;/body&gt;
...
</pre>
<p><strong>Important note:</strong> HTML code added via PreTreeFilterHeaderFooter should be (almost) valid XHTML 
(see <a href="http://www.w3.org/TR/xhtml1/#diffs">XHTML 1.0: Differences with HTML 4</a>); 
in particular, all tags / attributes should be in lower case. <em>Almost</em> means that you don't need to specify
wrapping <tt>html</tt>, <tt>head</tt> and <tt>body</tt> tags for the header content.</p>
</dd>

<dt><a name="hide-headers">I've added headers and footers to my HTML pages, but how I can prevent them from showing up in the browser?</a></dt>
<dd>
Use @media css rules setting 'display: none' or 'display: block' for header/footer blocks on different media.
</dd>

<dt><a name="hires-images"></a>Is there a possibility to create pdf documents with more than 72dpi using html2ps?</dt>
<dd>You may make a page with high-resolution images and set their on-page height and width using 
<code>height</code> and <code>width</code> attributes. 
HTML2PS does not resample images, just outputs them to PDF and provides the scaling factor. 
</dd>

<dt id="css-media">Can I control media size / margins via CSS?</dt>
<dd>
Yes. Use <a href="compatibility.css.3.html#media">CSS 3 'size' and 'margin'</a> properties. In addition,
html2ps provides '-html2ps-pixels' property which allows you to override 'pixels' value specified 
in pipeline configuration code.
</dd>


<dt><a name="pages-batch"></a>##PAGES## directive always displays 1 in batch mode!</dt>
<dd>Yes, it is a documented feature. ##PAGES## always refer to the number of pages in file being processed.
</dd>

</dl>

<h2 id="api">API</h2>
<dl>
<dt id="api-localfile">How could I convert HTML file from my local drive?</dt>
<dd>Use example file in <tt>samples/sample.simplest.from.file.php</tt> as a starting point.</dd>
<dt id="api-frommemory">How could I convert HTML code contained in a variable?</dt>
<dd>Use example file in <tt>samples/sample.simplest.from.memory.php</tt> as a starting point.</dd>
<dt id="api-security">Can I convert a page using some authentication mechanism using the html2ps webinterface?</dt>
<dd>Out-of-the-box &ndash; no. Depending on the type of the authentication you <em>may</em> override the fetcher
object with your custom one able to bypass authentication. Still, the <strong>recommended</strong> approach
is html2ps API usage; in this case, you store your HTML code in a PHP variable instead of outputting it to the browser
and call conversion engine directly.</dd>
<dt id="api-relative-path">I'm using API to convert files and images and / or CSS files seems to be ignored.</dt>
<dd>
Most likely, you're using relative URLs and, at the same time, converting either HTML string from memory or 
local file. In this case script doesn't know the base URL to use while resolving relative paths, so 
these URLs are ignored. You have two options in this case:
<ul>
<li>Change relative URI to absolute in your HTML code</li>
<li>Implement 'get_base_url' function in the fetcher object you're using so it return valid meaningful value.</li>
</ul>
</dd>

</dl>

<h2 id="fonts">Fonts. National symbols.</h2>
<dl>

<dt id="fonts-nonstandard">How can I use fonts other than standard (Times, Helvetica and Courier)?</dt>
<dd>Follow these <a href="howto_fonts.html" target="_blank">instructions</a></dd>

<dt id="fonts-euro">Euro symbol is not displayed</dt>
<dd>First of all, check if you provided correct information on the file encoding to html2ps; encoding vectors containing euro symbol are
'iso-8859-15', 'windows-1250', 'windows-1251' or 'windows-1252'. Alternatively, you may use UTF-8 or HTML entities                          
&amp;euro; or &amp;8364;.
</dd>

<dt id="fonts-cyrillic-ps">Cyrillic symbols are not displayed in PS output</dt>
<dd>Install <tt>sharatype-fonts</tt> package to your Ghostscript; 
the script is configured to use these fonts out-of-the-box.
</dd>

<dt id="fonts-greek-tonos">Greek symbols with tonos are not displayed in PS output; all other greek symbols rendered normally.</dt>
<dd>
<ul>
<li>install the unicode postscript .pfb fonts (for example, from <a href="http://canopus.iacp.dvo.ru/~panov/cm-unicode/">http://canopus.iacp.dvo.ru/~panov/cm-unicode/</a>)</li>
<li>remove the following default 'encoding-override' section from .html2ps.config, as it make greek text to use by default 'Symbol' font lacking 'tonos' symbols:
<pre>
&lt;encoding-override name="iso-8859-7"&gt;
  &lt;normal normal="Symbol" italic="Symbol" oblique="Symbol"/&gt;
  &lt;bold normal="Symbol" italic="Symbol" oblique="Symbol"/&gt;
&lt;/encoding-override&gt;
</pre>
</li>
<li>
update "fonts" (NOT "fonts-pdf") section to point to installed fonts, for example:
<pre>
&lt;fonts&gt;
  &lt;family name=&quot;times&quot;&gt;
    &lt;normal normal=&quot;CMUSansSerif&quot; italic=&quot;CMUSansSerif-Oblique&quot; oblique=&quot;CMUSansSerif-Oblique&quot;/&gt;
</pre>
</li>
</ul>
</dd>

<dt id="fonts-eastern">Chinese (Japanese, Arabic, etc...) symbols do not show on the page. What I need to do?</dt>
  <dd>First of all, you'll need fonts containing these symbols; in most cases 
    default fonts bundled with Ghostscript or PDFLIB will contain only Western/Central 
    European symbols. After you find fonts containing characters you need, you 
    should install them instead of the standard fonts, using the answer for this 
    question <a href="#fonts">&laquo;How can I use fonts other than standard (Times, 
    Helvetica and Courier)?&raquo;</a></dd>

<dt id="fonts-ttf-cache">I've installed/updated True-Type fonts, but it seems that ... (some mysterious problem) ... happens</dt>
<dd>First of all, clean a "parsed fonts" cache in 'fpdf/font' subdirectory (just remove all files). This could
solve most font-related issues.</dd>
</dl>

<h2><a name="forms"></a>Interactive forms</h2>
<dl>
<dt>When I try to submit the form, Acrobat responds with a &quot;Cannot handle content type: &hellip;&quot; message.</dt>
<dt>Every time I submit the form, I get a strange-looking result page in by browser.</dt>
<dd>
PDF interactive forms are not like HTML forms; you MUST modify the server-side script so it return FDF file 
instead of normal HTML in this case.
See <a href="http://partners.adobe.com/public/developer/pdf/index_reference.html" title="Opens PDF specifications download page at Adobe.com in new window">PDF Reference, v 1.6</a>, page 1026, par. 134 for futher information.
Also, you may check <a href=""></a> for a brief outline of PDF forms.
</dd>
</dl>

<h2><a name="frames"></a>Frames</h2>
<dl>
<dt>I have a page with frames containing a lot of text, but generated PDF contains only 1 page. Where's my content?</dt>
<dd>
As produced PDFs are static, you have no ways to scroll frame content. Thus, only initially visible frame content will be available. 
It is a feature.
</dd>
<dt>Some links inside the frames are not active even when I enable &quot;Render Hyperlinks&quot; option.</dt>
<dd>
As was stated previously, script may render only a part of frame content. So, if rendered part contains a local hyperlink
pointing to non-rendered part, this hyperlink will be disabled, as it points to nowhere.
</dd>
</dl>

<h2><a name="misc"></a>Miscellaneous</h2>

<dl>
<dt id="misc-size">Is it possible to reduce the size of output PDF file?</dt>
<dd>Yes. By default HTML2PS embeds fonts used during conversion in the generated PDF. You may disable this option by 
setting 'embed' attribute to '0' for these fonts in html2ps.config. Note that it will probably cause problems 
with national symbols on older versions of Acrobat Reader; also, this assumes that users have all fonts used in PDF 
files on their machines. Also, refer to the description of <a href="configuration.html#font_embedding_mode">FONT_EMBEDDING_MODE</a> configuration constant.</dd>

<dt>Is it possible to use a custom file name when outputting the pdf file? As of right now, the filename is long ugly string and doesn't look very clean.
Can I pass the script a varible such as &amp;saveas=thispdffile.pdf and use that for the file name when saving in the browser?</dt>

<dd>Yes. If you're using the web interface (html2ps.php file from distribution) you would need to replace 
<code>$g_baseurl</code> with <code>$_REQUEST['saveas']</code>  in the following piece of code near the end of html2ps.php:
<pre>
switch ($g_config['output']) {
case 0:
   $pipeline->destination = new DestinationBrowser($g_baseurl);
   break;
case 1:
   $pipeline->destination = new DestinationDownload($g_baseurl);
   break;
case 2:
   $pipeline->destination = new DestinationFile($g_baseurl);
   break;
}; 
</pre>
Also please note that by default output file name can contain only latin letters, digits, '-' and '_' signs, 
any other symbols will be replaced by underscores; 
you may change this behavior by hacking the <code>filename_escape</code> function in <code>destination._interface.class.php</code>.
<p>
If you're using API, refer to DestinationBrowser/DestinationDownload/DestinationFile class documentation.
