Since I upgraded to 2.1.5 I had not tried printing. I tried today and found the printer is now running s l o w. It prints a line then waits (for ~6 seconds). I did a fresh MAKEDEV - didn't help (oh and the same thing happens if I cat directly to /dev/lpt0 so it's not lpd...) >From /var/log/messages (on reboot): Aug 24 10:45:49 rhiannon /kernel: lpt0 at 0x378-0x37f irq 7 on isa Aug 24 10:45:49 rhiannon /kernel: lpt0: Interrupt-driven port In the config file used to build this kernel I have: device lpt0 at isa? port? tty irq 7 vector lptintr device lpt1 at isa? port? tty device lpt2 at isa? port? tty And no errors were logged in /var/log/lpd-errs I checked that I'm not using irq7 elsewhere. HOWEVER The problem disappears with lptcontrol -p so it looks like some sort of interrupt problem. (There were no probs before the upgrade). One problem is that I don't know how to monitor the parallel com port. Are there any other useful commands? Peter
