How to set up the HP LaserJet 4M?
HP Laserjet 4M I solved the problem by building a serial cable based upon the pinouts supplied by HP in their manual. Please note that the LJIII cable does not work. In particular, pin 1 from the DIN plug must be connected to pin 6 of the DB25. I used 38500 bps on both sides, and the 600 dpi ppd. Emulex offers the NETJet network interface which speaks lpd protocol, unlike the HP unit. 8.17 Laserwriter NTX & NEXTSTEP Laserwriter NTX This are the pin assignments.
