The "problem" is that your printer port was being driven by interrupts and this was somehow not working -- the interrupts storm message you reported. I can't tell you the why, except that it's happened to me on several PCs. I regularly turn off interrupts on the ppc in the BIOS as well, just be very sure. Why did your fix work? Because you have instructed the port to not use interrupts. Re-read the ppc man page until it makes sense. If you don't know what an interrupt is, then try finding a book on PC hardware or search google. I'm sure there's a wiki or something out there somewhere -- there usually is :) --Alex
