I have had problems with CUPS in two machines. Discovered it was due to
permissions not properly set.
Found which device corresponded to the printer (this changes after
printer is switched on/off/on):
$ lsusb | grep Epson
Bus 002 Device 004: ID 04b8:0838 Seiko Epson Corp. CX7300/CX7400/DX7400
Permission of device:
ls -l /dev/bus/usb/002/004
crw-rw-r-- 1 root lp 189, 131 Dez 2 07:54 /dev/bus/usb/002/004
In my case, it was not "root lp".
Using ID from lsusb above, changed udev rules, by adding:
$ ls -l /etc/udev/rules.d/10-usbprinter.rules
-rw-r--r-- 1 root root 104 Nov 8 12:32 /etc/udev/rules.d/10-usbprinter.rules
$ cat /etc/udev/rules.d/10-usbprinter.rules
ATTR{idVendor}=="04b8", ATTR{idProduct}=="0838", MODE:="0664", GROUP:="lp",
ENV{libsane_matched}:="yes"
and it worked. If you do not have sane installed, only need the part up
to "lp".
[]s,
Fernando
