hi John,

i'm using a 2 year old Epson 7600, Mac Os X drivers using a G5. all the 
test prints and nozzle checks are clear, no banding problems either. 
the reason i say there is a spooling problem is that ever since i got 
the printer i periodically would have strange prints come out of it, 
usually after an episode of a 'command error' message ( a command error 
is said to occur if the data being sent to the printer is damaged 
somehow, or a confusion with the appropriate print driver occurs). the 
other day i was plagued with these errors and i always notice that once 
i am able to make a print after a spat with an error alert shutdown the 
subsequent print has color issues, and at times banding problems (not 
the sort of banding associated with clogs but the kind that look to be 
part of the print file). sometimes these prints shoot out of the 
printer at 360 dpi instead of the intended 1440 dpi put into the 
printer dialogues. i think these things are indicative of print 
spooling errors. i don't like the fact this is happening since it can 
ruin the printing process and waste paper.
