I ran a KDE workstation install with a brand new Dell GX1 PC. It did not
find LPT1. Printtool could not detect any of the three LP ports.
In the Printing HOWTO it described how the printing modules had been
3. Kernel printer devices
3.1 The lp device (kernels <=2.1.32)
3.2 The parport device (kernels >= 2.1.33)
3.3 Serial devices
This pointed me to parport.txt in the rpm file
This doc told me to add this at boot time
Eureka..printtool finds the printer!!
This is fixed in 6.2 (specifically, in modutils.)
