USB Printer device problems

[haydn griffiths]

I have 2 printers (HP3030 and HP1600) connected via USB to a Redhat Enterprise Linux 4 server.  Using the GNOME printer tool, the printers and setup to be shared across the network. During setup each printer queue is associated with one lp device.( either lp1or lp0).

If the server is restarted/ printers are started in a different order/ one printer is not started then the device the printers are associated with can be different to the orginal printer queue settings. Eg . during the queue setup the HP1600 was associated with device Lp0 – while the printers were started in a different order of the HP3030 is not available , the HP1600 is now associated with the device Lp1. The printer queue for HP1600 still points at Lp0 which means that when users try to print to the queue, the print job lands in nirvana.

Is there a way of :

a)fixing a printer to a certain device and not letting them be dynamically associated ?

b)making the queue automatically associate to the correct device number

c)another solution ?

Thanks
