Direct Feed Commands to Printer and Pgnoring paper jams

Im working with a small team at the University of Washington in an effort to explore the possibility of 3D printing with HP printers. I was curious if it was possible from the driver level to send paper feed (both forward and reverse) commands to feed paper forward manually. This is useful for us because the print head would be mounted on a flat surface and as it prints it moves forward across the surface at the same rate as paper would be fed. The problem is that at the end of a line it needs to return to its original position. Thus it would be very handy to be able to spool the paper back using the printer itself as opposed to having to tacking on another device to do this. Im curious if this would be possible to do from the driver level or command line level. Also I am curious if it is possible to override the paper check mechanisms though software as opposed to hardware as most modern printers have 2 or more checks and it would be much more convenient to do a software override as opposed to tricking the printer in a mechanical way.
