I use a laser printer for most of my printing, so I only use my Epson
Photo 890 when I need to print color.  I never bothered to set up print
spooling for it, and just point ghostscript at it.  One problem I ran
into is that anything I attempt to print after a power-on gets turned
into garbage that prints a few funky-looking characters at the top the
page and then ejects the page unless I first run "escputil -n -u -r
/dev/ulpt0", which seems to send a magic escape sequence to the printer
that puts it in the proper mode.  I haven't had a time to investigate
further.
