Well, now I've got it really screwed up.
localhost:631 worked. I went and downloaded a PPD file for my HP2610 printer. I wasn't sure what to do with it, however.
I fiddled around using the printer management tool, and now when I try and print, I get a page single page with something like:
%!PS-Adobe-3.0 %RBINumCopies: xxxxx
And a lot of other meaningless garbage.
Before, my printer worked fine (color and all), except it just had an extra blank page.
Now, it doesn't work at all from Linux. :-(
I'd be happy if it was back the way it was, but I can't remember how I got it that way to begin with.
