If you get errors while giving insmod ppa as given below:
root# insmod ppa Using /lib/modules/version/kernel/drivers/scsi/ppa.o /lib/modules/version/kernel/drivers/scsi/ppa.o: unresolved symbol parport_register_device_Rf274b881/lib/modules/version/kernel/drivers/scsi/ppa.o: unresolved symbol parport_unregister_device_Rb0814cd3 /lib/modules/version/kernel/drivers/scsi/ppa.o: unresolved symbol parport_release_Rf8ec22de /lib/modules/version/kernel/drivers/scsi/ppa.o: unresolved symbol parport_claim_R4c7222c6 /lib/modules/version/kernel/drivers/scsi/ppa.o: unresolved symbol parport_enumerate_Rbc847709 /lib/modules/version/kernel/drivers/scsi/ppa.o: Note: modules without a GPL compatible license cannot use GPLONLY_ symbols
The problem is that you did not add a printer to your system in 'Printer Configuration'.
Before you do 'insmod ppa' you MUST add a printer. Click on
KDE-Start-Button->System->Printer-Config and add a printer by name
'sometestprinter' using /dev/lp0 (or lp1, lp2 check the output from dmesg | more).
Now, test the printer which you added by giving:
/etc/rc.d/init.d/lpd restart . If the lpd daemon starts then the printer is
configured properly. Now try
bash# insmod ppa bash# insmod lp
