Getting PuTTY to print to Konica Minolta Multifunction Printers secured by PageScope

We have been unable to passthru print using PuTTY (or its offshoot KiTTY) to several Konica Minolta multifunctional printers which are secured by KM's PageScope. I have been able to get Procomm Plus 4.8 and another terminal emulator, QVT Term to print to these printers. However the latter software does not work on Windows 7, so we have gone to KiTTY to replace it.

Does anyone have any idea how to fix this issue?
