Re: [Epsonepl-users] Easiest installation and possible changes to printing system

What exactly does "./ps2epl epl_test.ps /dev/lp0" says, after you do make
install (you need to be root to access /dev/lp0)? There should be
about 20-lines of debug messages per page attempting
to print. And your printer model?
(the script defaults to 5700L). Even if you get the model wrong (.e.g if
you have a 5900L or a 5800L), the green light on the printer should flashes a
few times, and then the red light comes on. If these didn't happen,
your printer cable is broken. If you tested as non-root, you should see
"permission denied" at least. What message did you see!!!???

Here are some answers, and some questions, and some tips, somethings to
try, etc. (some of these should go into the next version of the FAQ...)
but honestly your "doesn't work" is too brief - please help others to
help yourself, by providing details.

(1) is gs in a normal user's $PATH? Type 'gs -h', and also "which gs".
I read that some printing systems on some distro put gs (particularly
ESP ghostscript) in a hidden location accessible by default only
by the print system itself. (in which case there should have been a message
"command not found"!).

(2) LPD-O-MATIC is a layer on top of this plugin in. You need the plugin
for printing, and LPD-O-MATIC to add some user-friendliness.

(3) the rpm dependency check is rather redhat-centric (i.e. it is
a bug/limitation). but if you can verfiy that you can run "gs -h",
and it has the right version, ijs device present, etc
it should be safe to do "rpm --nodeps -i <binary rpm>" on a recent
linux distro. (This is what I do on Slackware).

(4) (do this as root!) type 'echo rubbish > /dev/lp0' . The green
light on your printer should switch off and the red light comes on.
(yes, this crashes your printer and now you have to reset it by switching
it off and on again). If your printer didn't crash, your printer cable
is broken, your kernel's parallel port support is broken, or the physical
parallel port hardware on your motherboard is broken.
