Yeah, I had very similar problem with my USB connected printer.  It 
worked on  FC2.  Upgraded machine.  Now printing works from local 
machine, but anything sent from remote hosts ends up in black hole.  Log 
files indicate printing went fine!?

I solved problem for Windows systems by using PostScript driver on 
Windows side.  Windows boxes are now sending PostScript with appropriate 
content-type header.

However, other Linux boxes (configured to use IPP to connect to my Cups 
printer server) still can't print, and I was unable to find solution. 
Trick with PostScript that worked for Windows doesn't work for Linux 
(probably since Linux is sending different content-type, something along 
the lines of application/ipp or similar).

Basically, sounds like a bug in Cups somewhere.  When I talked to Cups 
people, they simply refused to accept it might be a bug without even 
looking into it, and redirected me to a support forum that wasn't much help.

If you manage to find solution, let me know.  I'd be interested to hear 
how you solved it.
