epson stylus c82: usb+udev

hi. i had my printer working quite well for some time. when i switched to 2.6 and finally to udev i lost overview and control over my system. sound devices i make on my own will be overwritten, usb printer won't be detected at all (no /dev/lp0 or /dev/usblp0) after turning it off and on again and while i got a device i could talk to (/dev/lp0) my printer wouldn't spit out a site because of an error (something with status 22).

[rant]
printing will be broken every release of cups/ghostscript/gimp-print/whatever, old howtos no longer work and it takes often days to weeks to get someone to use enough spare time for another howto to fix a problem, that will occur just the other week again. i know linux is moving and evolving, but some problems are just to mind bogingly stupid, that i wonder how everyone can overlook them all of the time. printing (next to gaming) is one of the reasons i always wonder, if i will make me go back to windooze again, but then i remind myself, that windows will hold exactly that kind of problems for me, for about every aspect i can think of...

I have the same combo working very nicely ;-)

I made: :/etc/udev/udev.rules:
# Epson C82
BUS="usb", SYSFS_serial="0HS510304210308460", NAME="lp_epson"

(change the serial into yours !!!!!!!! )

and told CUPS (/etc/cups/printers.conf) :
[snip]
<Printer epson>
Info
Location
DeviceURI usb:/dev/lp_epson
[snip]

And all is well.
I believe the trick is to stay away from the obvious device names like (usb)lpx.

ok it seems that the rules.conf thing isnt needed.udev creates the usb printer device node in /dev/lp0 even if its a usb one. so what i did was changing to
DeviceURI usb:/dev/lp0

I had the same issue with /dev/lp0

Once I had written the rules in udev.rules (see the guide mentioned above) it worked well, creating the device /dev/usb/lp0 and the symlink to dev/Epson

well... my printer worked with the 5.0.0_alpha1 drivers of gimp-print. they are masked now, and reverting back to 4.2.6 kicked my printer out of order again. i'll install the alpha drivers again, i think.
