I can’t print

• Since both Linux Printer Package and MFP driver make a
symbolic link to “lpr” printing command, which is
commonly used on Unix clones, it is not recommended to
use both package on the same machine.

• If you still want to use both packages simultaneously,
please install the LPP first.
• If you want to uninstall only one of them, please uninstall
both packages and install that one you want to use again.
• If you don’t want to uninstall MFP driver and install it
again, you may make the necessary symbolic link

Please avoid changing print job parameters (via SLPR
utility, for example) while a print job is in progress. Known
versions of CUPS server break the print job whenever print
options are changed and then try to restart the job from
the beginning. Since Linux MFP driver locks MFP port while
printing, the abrupt termination of the driver keeps the port
locked and therefore unavailable for subsequent print jobs.
If this situation occurred, please, try to release the MFP
port.
