I had a similar problem. If you read the parport.txt in
/usr/src/linux/Documentation, it explains that the new parport code
changes the way lp devices are assigned. In the older kernels, there is a
static relationship between the lp devices and the I/O port. My printer
port was at 0x378 which was lp1 under 2.0 kernels, but in the later dev
kernels it becomes lp0. All I needed to do to fix printing here was to
change my /etc/printcap to send output to lp0 instead of lp1.
