For the record, USB->Parallel doohickies rarely if ever work for driving things like EPROM burners. They do *not* support the sort of manual bit-flipping on the port that those things require. (They're hardwired to drive *printers* and make a parallel printer look like a USB interfaced one. The EPROM burner software expects the parallel port to be an 8 bit hardware port at address 0x378/0x3BC/0x278 to which it can directly shove and read bits.)
Of course, there *are* those "straight from China" EPROM burners that sell for only $50 or so and *do* work with USB, so the point is still somewhat valid. (The only reason I'm bothering futzing with my old DOS driven one is it supports a few obscure old-style EPROMs that newer ones often don't, like the 2532, which happens to be useful for what I want an EPROM burner for.)
