QTR-Quadtone RIP

Hi,

This message is to request help with a problem with the Quadtone RIP 
used for an Epson 2200 loaded with the Piezography K7 inkset.  The 
Quadtone RIP version is 2.2.4, which is the most recent from what I 
can tell.  

The problem is that most of the time the TIF files sent for printing 
do not print.  Instead, the printer grabs the paper, but the paper-
out light comes on.  The print status goes from spooling to printing 
and the print size increases to a certain point (21.4 MB for my most 
recent image).  Then nothing happens.  If I retry it several times 
and I'm lucky, it will print.  But most of the times it just repeats 
what it did previously.  

All files are flattened and are 8 bit grayscale.  Changing the size 
and resolution of the TIF file has no effect.  Re-starting the 
printer has no effect.  Re-starting QTR also is without effect.  
Changing the paper size settings and all other settings (including 
resolution) has no systematic effect. About 10% of the time re-trys 
will cause Windows XP (home edition) to lock up, requiring re-start.  
Re-starting the computer does not correct the problem. Disabling all 
firewalls and anti-virus software has no effect.  Finally, 
uninstall/re-install of QTR had no effect.  

This problem seems to be intermittent.  There are times when I can 
print several files in a row before it jams up.  The printer works 
perfectly every time with the Epson driver, either before or 
immediately after unsuccessful attempts at printing with QTR.  There 
are no apparent communication problems between computer and printer.  

If anyone else has dealt with this I would appreciate your help.  
While the K7 inkset is nice, if it can't be used without a 
considerably more expensive RIP, then it's probably not worth having.

Thanks in advance for your input.

Tony
