Troubleshooting 7.7 Common Linux Problems Problem I can't change settings in the configuration tool. I am using the KDE desktop but the configuration tool and LLPR won't start. I just installed this package but can't find entries in the KDE/ Gnome menus. I get a "Some options are not selected" error message while editing the printer settings. I can't make a printer the system default. The N-up setting does not work correctly for some of my documents. I am using BSD lpr (Slackware, Debian, older distributions) and some options chosen in LLPR don't seem to take effect. Possible Cause and Solution You need to have administrator privileges to be able to change global settings. 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. Some versions of the KDE or GNOME desktop environments may require that you restart your session for the changes to take effect. 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. 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, and 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 an 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 feature is achieved through post-processing of the PostScript data that is 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 that rely on post-processing if the document being printed isn't compliant. Legacy BSD lpr systems have a hard limitation on the length of the option string that can be passed to the printing system. As such, if you selected a number of different options, you may have exceeded the length of the options and some of your choices won't be passed to the programs responsible for implementing them. Try to select fewer options that deviate from the defaults, to save on memory usage. 7-12 Service Manual Samsung Electronics

7.7 Common Linux Problems
I can't change settings in the
configuration tool.
You need to have administrator privileges to be able to change global
settings.
Problem
Possible Cause and Solution
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.
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 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 that rely on post-processing if the document being printed
isn't compliant.
I am using BSD lpr (Slackware,
Debian, older distributions) and
some options chosen in LLPR
don't seem to take effect.
Legacy BSD lpr systems have a hard limitation on the length of the option
string that can be passed to the printing system. As such, if you selected a
number of different options, you may have exceeded the length of the
options and some of your choices won't be passed to the programs
responsible for implementing them. Try to select fewer options that deviate
from the defaults, to save on memory usage.
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 "print-
tool" 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, and 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 an 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.
