Common Linux problems

CONDITION	SUGGESTED SOLUTIONS
The printer does not	• Check if the printer driver is installed in your
print.	system. Open Unified Driver configurator
	and switch to the Printers tab in Printers
	configuration window to look at the list of
	available printers. Ensure that your printer 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 printer 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.
	• Check 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).
Some color images	This is a known bug in Ghostscript (until GNU
come out all black.	Ghostscript version 7.05) when the base color
	space of the document is indexed color space
	and it is converted through CIE color space.
	Because Postscript uses CIE color space for
	Color Matching System, you should upgrade
	Ghostscript on your system to at least GNU
	Ghostscript version 7.06 or later. You can find
	recent Ghostscript versions at

	while printing, the abrupt termination of the

	situation occurred, try to release the port.
