modify printer driver to work with 64-but machine and make it do “half-cut” feature

The sony up-dr150 is the industry standard dye sublimation printer. It prints off a roll of paper, and cuts a 4x6 photo strip off of the roll when done.
Because this is an old printer, the driver only works with 32-bit machines. I would like it to work with 64-bit machines
I wish to get the driver revised to make it work with 64-but machines and allow the printer to do a "Half cut, basically yielding 2 x 2x6 photo strips instead. I know drivers have been made for other sony models, but because of the fact that the up-dr150 is discontinued, there is no further driver development.
