----ERROR MESSAGE----

This occurs on two installations:

install 1:
Slackware 10 with printer HP 4600 color laser
install 2:
Slackware 10 with printer Epson Stylus Photo 870

Using print direct works with HP 4600 color laser
Using print direct doesn't work with Epson Stylus Photo
870 (I get a grey block printed instead of printout)
