I've made a wrong assumption that USB to LPT cables work just fine with UrJTAG. I've got one, which is based on CH340 chip. The cable is natively supported by kernel and by Windows. It's being picked up by usblp kernel module.

Is the chip suitable to do the job?
If yes, which cable driver shall I use as a template?
Many thanks, in advance, for your replies!
