Interrupt-driven operation is something that some newer printers use for higher speeds. Most older printers (and most new printers, AFAIK) use 'polling', a different method for the CPU to monitor the port. It basicaly has to do with CPU usage and efficiency in making sure the right bits get to the right places. If you're printing just fine, don't worry about it, IMHO. If you've researched your printer, and it should be using interrupts, and you feel like recompiling your kernel to include procfs, go for it. That is what the error message means. Good luck, Steve
