[Solved] All-in-one Epson CX5200+cups-1.2.6 (and udev-103?)

[Tuvok]

After updating to the new cups (and new udev) the printer stopped working.
After modifying the printer over the cups localhost:631 web interface, which now selected another device uri:
Device URI: usb://EPSON/Stylus%20CX5200
it still didn't work. It now showed:
Epson_CX5200 (Default Printer) "/usr/libexec/cups/filter/rastertoprinter failed"

After reading
/var/log/portage/elog/net-print:cups-1.2.6:20061201-232102.log:

http://linuxprinting.org/show_printer.cgi?recnum=Epson-Stylus_CX5200 recommends the Gutenprint driver and Gutenprint is still marked unstable on all architectures.

You might like to try it, however.

• Add media-gfx/gimp-print to your /etc/portage/package.keywords
• "emerge -av media-gfx/gimp-print" — you should get 5.0.0
• When it is installed run, as root

  Code:

  cups-genppd.5.0 -M -v|grep -i CX5200

  which should show

  Code:

  escp2-cx5200        Epson Stylus CX5200

• Create the PPD file with

  Code:

  cups-genppd.5.0 -v escp2-cx5200

  which will (may, you may have to create /usr/share/cups/model/gutenprint/5.0 and run it a second time) create the PPD
• Now delete the printer you have created and recreate it again. If you take the "Add this printer" option then it will choose a name for you (you had "EPSON_Stylus_CX5200_USB_#1). If you would like to choose your own name, click on the plain "Add Printer"

I have the same problem but my printer is connected with ethernet [socket://192.168.1.5:9100].

In the web interface doesn't find any printer (logically) and I can't install it like Tuvok.

My printer is Epson CX6600. Thanks.

EDIT: Just upgrade to gimp-print-5.0 solve the problem, thanks!
But I need to choose a non-recommended driver.

Thanks, wynn, for your advice. Adding the printer worked flawlessly.
Then for some strange reason printing didn't work. It either showed "printer not connected" or was hanging at "printing page 1 4% [...]".
It turned out that somehow /dev/usb/lp0 became root:scanner. chgrp'ing to lp helped immediately.

Now I have a very strange (permission?) problem that kooka on non-root account doesn't work (even selecting Settings->Select Device doesn't show a dialog box) although its device has the right group (which my account is also in):

Changing the permission for the device which corresponds to the scanner
