Server:
distro: RedHat 9
cups version: From RedHat RPM: cups-1.1.17-13.3.0.3
kernel: From RedHat RPM: kernel-2.4.20-30.9
Interfaces:
	public: eth0.pub - 137.205.x.y
	private: eth0.print - 10.0.0.254
Queues:
	<Printer pr1> DeviceURI lpd://10.0.0.1/ </Printer>
	<Printer pr2> DeviceURI lpd://10.0.0.2/ </Printer>
Classes:
	<Class cl> Printer pr1 Printer pr2 </Class>

Printers:
	pr1 (HP LaserJet 8150dn) - 10.0.0.1
	pr2 (HP LaserJet 8150dn) - 10.0.0.2

I would like the cups scheduler to know what printers are available, 
either by pinging the printer regularly, or by assuming the printer is 
available and if the tcp connection times out, moving the job to 
a different queue in the same class.
And if all this could be on the webpage (http://server:631/classes/cl) 
then that would be nice.

Thanks,

Ashley GC.
