I have to back @JeffSchwenk up here, is there not some way this could be done with a laser jet? print multiple copies, mutli-tray printer with different color paper, something?
My consulting brain is kicking in, (must tame the beast!!!) - how many copies do they print and where do they go? We use a tool called PrintBoss from Wellspring Software to route copies to multiple printers. (We use it for printing ACH checks as well for better security) It's cheap and it works!
Just thinking.
