I can’t make a printer the | • In some conditions, it may not be possible to change the | |

|
| 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. |
