I have my SUSE 10.0 machine hooked up to an HP laserjet printer. I can print documents, web pages, etc. just fine. I installed the Adobe Reader plugin for Mozilla Firefox and PDFs always print to A4 paper size (and thus, my printer prompts me for A4 paper, which I don't have). How can I get PDFs to print to 8.5" by 11" paper, just like everything else is printing to that?

Have you looked at the printer configuration to see what the default paper format is? Since Linux is international and SUSE hails from Germany A4 could be the default.

I couldn't find the paper format setup in the SUSE printer confiuration. Where is it?

And then, why would everything else print just fine, and only PDFs from Adobe Reader print in A4?

The easiest way to reconfigure your printer is in cups. Point your web browser at http://localhost:631/ to get to the cups administration interface.

Firefox sits there, trying to load that address, indefinitely. It never comes up.

1. Make sure cupsd is installed (check yast) and running (rccups status)
2. Turn your firewall off; if it works then, you need to open port 631 before you reenable the firewall
3. Once you get to the cups gui, you may need to add a user to the cups digest. man lppasswd to get started, if you need additional help post back

I don't think this is a cups problem, as I have exactly the opposite experience. My Acrobat Reader in SUSE 10.1 defaults to "letter", and here in Australia we use A4. Other people in this part of the world have the same problem. There is no way I can find of resetting the default in Acrobat Reader.
This is a really dumb bug as if you look at the document properties in Reader it knows perfectly well that the document is A4 or whatever.
Everything else prints to the KDE default of A4, I just have to remember to go into Properties and selct A4 when printing from Reader.
A solution might be to use KPDF or Ghostview instead.
Adobe don't seem to have a proper bug-logging system, but I have notified them, with no response as yet.
