4.2.2.10 Common Linux problems

Condition
The machine does • Check if the printer driver is installed in your system. Open Unified Driver
not print configurator and switch to the Printers tab in Printers configuration window to look at
the list of available printers. Make sure that your machine is displayed on the list. If
not, invoke Add new printer wizard to set up your device.
• Check if the printer is started. Open Printers configuration and select your machine
on the printers list. Look at the description in the Selected printer pane. If its status
contains "(stopped)" string, press the Start button. After that normal operation
of the printer should be restored. The "stopped" status might be activated when
some problems in printing occurred. For instance, this could be an attempt to print
document when port is claimed by a scanning application.
• heck if the port is not busy. Since functional components of MFP (printer and
scanner) share the same I/O interface (port), the situation of simultaneous access
of different "consumer" application to the same port is possible. To avoid possible
conflicts, only one of them at a time is allowed to gain control over the device. The
other "consumer" will encounter "device busy" response. You should open ports
configuration and select the port assigned to your printer. In the Selected port pane
you can see if the port is occupied by some other application. If this is the case, you
should wait for completion of the current job or should press Release port button, if
you are sure that the present owner is not functioning properly.
• Check if your application has special print option such as "-oraw". If "-oraw" is
specified in the command line parameter then remove it to print properly. For Gimp
front-end, select "print" -> "Setup printer" and edit command line parameter in the
command item.
• The CUPS (Common Unix Printing System) version distributed with SuSE Linux 9.2
(cups-1.1.21) has a problem with ipp (Internet Printing Protocol) printing.Use the
socket printing instead of ipp or install later version of CUPS (cups-1.1.22 or higher).
