Hi,
I have been working on a printer-friendly script which will allow me to produce printer-friendly pages for those pages which are produced dynamically (i.e. that don't actually exist on the server).
It is almost working except that I get two problems, which may be related.
1) The script is slow
2) It displays the following:
- c3 fd0
- 52 59d
in the page's contents.
I have no idea where they have come from. To see what I mean take a look here:
http://www.ski-info-online.com/skiResort-print1.php
and click on the "Print Review" button.
Does anyone have any ideas how these numbers are being generated to the page?
Thanks

Below is a copy of the print.php script.
