Just to add a datum point to the discussion, I have tried a PCMCIA parallel port adapter (Quatech SPP-100, rev H) to drive a Needham's device programmer. Short version: Okay with printers, didn't work to drive the programmer.
This was a couple of years ago and the hardware, firmware, & drivers may well have improved since then. Probably won't hurt to give one a try, and, after all, a device programmer != a dongle.
