replace multi-part invoice form

["Jim Franz" <franz400@xxxxxxxxxxxx>]

Need ideas for replacing a multi-part form printed on twinax printers (Epson). 
3 parts - office(white), driver(blue), customer(yellow) - paper is carbonless.
Office copy stays in office, to match with driver's returned & signed copy.
Currently customer signs top form and driver leaves customer their yellow copy.
 
This is not UPS or Fedex - this is low tech, low wage drivers.
Drivers & pickers pull their paper from printer, so must be easy load & print.
Office people just enter the orders (5 - 7,000 month). This is food delivery.   

Managers like the idea of printing on blank paper, putting some color on 2nd & 
3rd copy.
Leaning towards color laser 3 drawer (i know the consumable may rule this out)
Office likes HP lasers....
They did already rule out (for now) colored paper in the correct order from 
single tray).

I know overlays & form printing. I'm wondering how most sites transformed 
twinax based
multipart forms into something else.
