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.

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.
