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. since the default queue in

 

 

LPRng is defined as the first queue in /etc/printcap,

 

 

therefore it is not possible for the Samsung 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.
