Common Linux Problems
Problem Possible Cause and Solution
I can’t change settings in
the configuration tool.
You need to have administrator privileges to be able to change
global settings.
I am using the KDE
desktop but the
configuration tool and
LLPR won’t start.
You may not have the GTK libraries installed. These usually
come with most Linux distributions, but you may have to
install them manually. Refer to your distribution’s installation
manual for more details about installing additional packages.
I just installed this
package but can’t find
entries in the KDE/Gnome
menus.
Some versions of the KDE or GNOME desktop environments
may require that you restart your session for the changes to
take effect.
I get a “Some options are
not selected” error
message while editing the
printer settings.
Some printers have conflicting settings, meaning that some
settings for two options can’t be selected at the same time.
When you change a setting and the Printer Package detects
such a conflict, the conflicting option is changed to a “No
Choice” value. You have to choose an option that does not
conflict before being able to submit the changes.
I can’t make a printer the
system default.
In some conditions, it may not be possible to change the
default queue. This happens with some variants of LPRng,
especially on recent RedHat systems that use the “printconf”
database of queues.
When using printconf, the
/etc./printcap
file is
automatically refreshed from the database of printers
managed by the system (usually through the “printtool”
command), and the queues in
/etc./printcap.local
are
appended to the resulting file. The default queue in LPRng is
defined as the first queue in
/etc./printcap
, therefore it is
not possible for the Linux Printer Package to change the
default when some queues have otherwise been defined using
printtool.
LPD systems identify the default queue as the one named “lp”.
Thus, if there is already a queue by this name, and if it
doesn’t have any alias, then you won’t be able to change the
default. To work around this, you can either delete the queue
or rename it by manually editing the
/etc./printcap
file.
The N-up setting does not
work correctly for some of
my documents.
The N-up feature is achieved through post-processing of the
PostScript data that is being sent to the printing system.
However, such post-processing can only be adequately
achieved if the PostScript data conforms to the Adobe
Document Structing Conventions. Problems may arise when
using N-up and other features relying on post-processing if
the document being printed isn’t compliant.
