I am nearing my wits end with regard to setting up a serial port connection to
an HP DeskJet 550c on a Sun 3/60 running NetBSD 1.3.2, can anyone help?
I can print text files without any problems, however when I send a graphics file
generated by ghostscript it manages one raster line and then proceeds to print
gibberish.
 Here is my setup, any comments on this would be much appreciated.
1. Null Modem Cable Pin-out (4 wire)
 Sun 3/60 DeskJet
 TxD 2-->3 RxD
 RxD 3<--2 TxD
 SG 7---7 SG
 CTS 5<--20 DTR
2. Printer Switch Settings
 A1 down |
 A2 down |_ Default Character Set (PC-8)
 A3 down |
 A4 down |
 A5 down |_ Paper Size (A4)
 A6 up |
 A7 down Carriage Return Defn. (CR only)
 A8 down Perforation Skip (On)
 B1 up Text Scale Mode (66 lines/page)
 B2 down RAM Cart. Defn. (Downloading)
 B3 down
 B4 down
 B5 down |_ Baud Rate (19200)
 B6 up |
 B7 down |_ Parity (none)
 B8 down |
3. Printcap Entry
