Update to the current CUPS version (the new feature was already 
introduced earlier, but I do not remember the CUPS version), restart the 
daemon, run "lpinfo -v", and you will see printer-specific URIs (ex: 
"usb://HP/PSC%20900%20Series?serial=MY21AC21J6WP" instead of 
"usb:/dev/usb/lp0"). Change the URIs of your print queues to these new 
ones and jobs will always go to the correct printer, independent of the 
sequence how you have turned on your printers.
