I salvaged a stepper motor from a hp laserjet 1020 printer that had broken. The motor specifications are on the second page of the pdf listed below or further down for a cut/paste of the info.

My question is can I use this stepper, in combination with say 4 nema 17's or 4 other mix and match printer motors from other broken printers, to drive my prusa.
I've done the vitamins and plastics stage of my prusa and am moving onto the electronics phase. I have a great local support group for the the build but I thought I'd post in this section with my questions first for this specific issue before I bug them.
