So I added the following code to the hotplug script section in the USB support…
p910nd -f -b /dev/usb/lp1 1
This allows multiple printers to be recognized, however they are assigned ports based on the order they are connected/turned on.
Is there a way to have them assigned static ports instead of dynamic?
The two printers use different paper and are turned off at night, and then sometimes they switch ports when turned on out of order the next day.
