printer problem (prints postscript source, not document)

[Miles Bader <miles.bader@necel.com>]

My work has a combo copy-machine/fax/printer that works great with
windows (and seems really fast), but I can't seem to get it working
properly with debian/cups.

The printer model is:  "Canon iR C4580F"

I managed to locate it on the net, and configured it with cups'
webpage-configuration stuff, and even found a .ppd file for it on
Canon's website (no easy task, as naturally they distribute everything
as windows installable archives...).

The printer seems to use the "IPP" protocol, with a URL of
"ipp://dhypr434:631/ipp" (I've attached the /etc/cups/printers.conf
entry to this message).

The problem is that when I print to this printer, while it _does_ print
something, it prints the _postscript souce code_ for whatever I'm trying
to print!  This seems to happen no matter what input I feed cups
(postscript file, pdf file, ...) or what frontend I use (lpr command
from .ps file, mozilla print command, evince print command etc).

So, for instance, a very simple 1 page postscript file (see "test.ps"
attached to this message) results in the printer printing about 8 pages
of postscript source code.

Upon examining the postscript source code thus printed, I see two
things:

   (1) It's obviously the same postscript I fed it, but has been
   "augmented" by some filter along the way, fleshing out the various magic
   comments and adding some setup code etc.  I assume cups does this, but I
   don't think it's the problem.

   (2) The source code is "stair-stepped", with newlines only moving
   vertically.  This suggests that whoever converted the postscript into
   text for printing was expecting a windows line-ending convention.

I suppose (2) could be part of the problem, if somebody along the way is
expecting postscript using windows line-endings, and gets confused
because it gets only unix-style newlines.

If anybody has read this far, do you have any suggestions on where I
could look for the problem?

[Using wireshark, I can see lots of negotiation between cups and the
printer when I print something, but I'm not really sure what's correct
and what's not...]

Thanks,

-Miles
