SYSTEM REQUIREMENTS

Required:
- PHP 4.1.0 or newer (PHP 5 supported too)
- native _OR_ Active-Link DOM XML extension installed

Recommended:
- 'gzlib' PHP extension
- 'iconv' PHP extension

In order to view generated postscript files, you'll need some PS-handling software
installed on the client computer. Ghostscript (7.05 or newer) and GSView are good
examples. Also, you can convert posctscript files to PDF using Adobe Acrobat Distiller.

Additionally, following requirements should be met to convert generated PS to 
PDF server-side:
- 'ghostscript' package (version 7.05 or newer)
- 'ghostscript-fonts' package
- PHP 'exec' function should be enabled (so, PDF conversion will not work in
php 'safe mode')

FONTS 

--- Using non-standard fonts in PostScript (Ghostscript)

First of all, you'll need TrueType-compatible Ghostscript (most of them do)

--- Using non-standard fonts in PostScript (Adobe Acrobat)
--- Using non-standard fonts in PDF
If you're using server-side Postscript to PDF conversion

For the details regarding installation of TrueType fonts with Ghostscript see:
http://www.cs.wisc.edu/~ghost/doc/gnu/7.05/Fonts.htm

JAVASCRIPT & DHTML

No, not supported.

PHP EXTENSIONS ISSUES

Native PHP XML extesions is HIGHLY recommended. Active-Link extension 
lack several important features, which can cause processing to fail 
on miscellanous HTML samples. 

ADOBE ACROBAT COMPATIBILITY ISSUES

The script is configured to work with the Ghostscript out-of-the-box. 
As GS and Adobe Acrobat use different font names, you'll need to 
change .html2ps.config to match them.

IMAGE ISSUES

In general, image processing is the weakest part of the script; all images
are processed in pure PHP, making 

COMPRESSION ISSUES

By default, script tries to compress generated Poscript. Compressed Postscript
is 4-5 times less in volume than uncompressed, and most Postscript-related software
understands it.

You'll need gzlib PHP extension installed to generate compressed postscript. 
Script detects the presence of gzlib at run-time, so you do not need to change
anything in configuration files or specify any additional parameters to use 
compression ability.

Unfortunately, Adobe Acrobat Distiller does not support compressed postscript. 
In this case, you have only the following options:
1. Uncompress the file manually (all modern achivers do - WinZip, WinRar, 7-Zip etc) and
   feed it to the Distiller. 
   Pro: Smaller file size - less traffic and download time. 
   Contra: you'll need to do by your hands, wasting your time.
