The Brother MFC-8420 is a "BR-Script3" printer. As far as I know "BR-Script3" is Brother's own implementation of PostScript so that your printer is a PostScript printer and such printers do not have driver issues with Linux, see http://en.opensuse.org/Concepts_printing Likely the root cause is not in CUPS because --------------------------------------------------------- # echo -en "\rHello\r\f" >/dev/usb/lp0 bash: /dev/usb/lp0: Device or resource busy # fuser -v /dev/usb/lp0 # --------------------------------------------------------- looks like a contradiction in itself for me (the device file is "busy" but according to "fuser -v" there is no process which uses it) which indicates that "something is wrong" with /dev/usb/lp0 but I am no USB expert to make a final statement here. As long as # echo -en "\rHello\r\f" >/dev/usb/lp0 does not work, it is not possible to communicate with the printer so that any kind of CUPS setup cannot work. Therefore first and foremost # echo -en "\rHello\r\f" >/dev/usb/lp0 must work. To get CUPS out of the way for now, delete all your current print queues using as root # lpadmin -x <queue_name> in particular for example # lpadmin -x brothermfc8420 then stop and disable the cupsd using as root # rccups stop # insserv -r cups finally reboot to make 100% sure to have a clean state. After the reboot try again if # echo -en "\rHello\r\f" >/dev/usb/lp0 works. If it does not work, try # rmmod usblp # modprobe usblp # echo -en "\rHello\r\f" >/dev/usb/lp0 If this still does not work it proves that there is a low level issue (probably USB and/or kernel related). If # echo -en "\rHello\r\f" >/dev/usb/lp0 works, re-enable and start cupsd # insserv cups # rccups start and check if the CUPS usb backend recognizes your printer # /usr/lib/cups/backend/usb If the CUPS usb backend recognizes your printer you can set up the printer using any printer setup tool you like. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
