Hi friends, this is my first post to this forum ... I'll glad to help ... (if I can do that). I've a parallel printer attached to a Compaq ML350 box running SuSE Professional 8.0
The printer works fine, but the printing speed is the half of the regular speed. If I connect the same printer to other compaq (same model, same configuration, same cable) it prints a normal speed, but if I connect back to the Linux box its slow downs to the half of speed.
The printer is a Printonix using no driver (raw, generic text), I tryied no printing spool (doing a >/dev/lp0), lpr (BSD) and cups; all of them with the same results.
I saw an article at SCO's knowledge center where the SCO Uniware's 7 have the same problem due a Compaq's parallel port construction.
I don't have any dmesgs or port conflicts; the Compaq's BIOS only have three options (LPT1, LPT3 and disabled) ... the printer works fine, only at half speed.
Just a long shot, but perhaps you need to turn on lpt interrupts. Use tunelp to do this, probably "tunelp -i 7". -Nick
