 | 
| 
 | 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. |
