Continuous Print for OKI Printer - Firmware modification

We use oki c711 laser printer... this is a comum laser printer which is based on sheets feed, like A4, Letter, etc page sizes. We need to modificate firmware of printer that when we sent for example 10 copies of document to print, the printer doens´t ask for load next page sheet, and just continue to print on continuos roll. If you have any doubts, I would appreciate to explain better.
