Common Linux Problems Problem Possible Cause and Solution I can't change settings in You need to have administrator privileges to be able to affect the configuration tool. global settings. I am using the KDE desktop but the configuration tool and LLPR won't start. Maybe you do 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, and 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 6 queues in /etc/printcap.local are appended to the resulting file. Since the default queue in LPRng is defined as the first queue in /etc/printcap, 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, 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 Structuting Conventions. Problems may arise when using N-up and other features relying on post-processing if the document being printed isn't compliant. SOLVING PROBLEMS 6.23
