Epson printer stops printing but works on command line

[Pollywog]

My printer all of a sudden stopped printing from Gnome.  It was working a 
few weeks ago and I have not changed any configs and this is the error I 
get from the printer.  It prints this and then stops:

Unable to open command line file stc740p.upp
My printer is a Stylus Color 740 and I have not tried to print in several 
weeks, but as I said, I have not changed any configs and it does print 
from the command line, just not from Gnome.


thanks
