Tuboprint - anyone else using and getting printout?

[Gerry Tool]

I have a networked Canon PIXMA ip-4000 inkjet printer for which the only 
drivers I've found are in Turboprint 1.91.  This works great on FC3, 
Ubuntu 5.04, Suse 9.2 and a number of older releases.  It does not work 
on FC4Tx.

Turboprint installs, setup works and configuration works just great. 
When a document is "printed", the system is just as happy as can be.  If 
one didn't notice that nothing happens at the printer, one would think 
all is working.  The CUPS web interface thinks the printer is just fine 
and that the job was sent successfully.

I understand that Turboprint is not a supported app, but since it is the 
only choice available to use my color inkjet printer in Linux, I will be 
unable to continue using Fedora Core if it does not work in FC4, since 
one of my major activities is color photo printing.

I have filed a bugzilla report (#154777) - closed as NOTABUG, and have 
filed a report with the Turboprint developers with no response so far. 
I will be grateful for any suggestions to troubleshoot the problem.

Thanks.
