- if you just want to hook it up and be able to spew raw HP-GL at it from
- crufty command line proggies that belch HP-GL into a file, your best bet
- is to man printcap, man lpr, man lpd and create a printcap entry in
- the netinfo database using NetInfoMangler. The NeXT printer config
- stuff is all geared towards PS printers, not very helpful for vanilla
- line printers or plotters. You basically want to configure it as
- a raw line printer with no filters. Something like so:
-
- # br=9600 baud, mx=unlimited file size, lp=on ttya (serial port a),
- # ff=no form feed char
- # sd=spool directory in /usr/spool/lpd/hp7550a (create this)
- # pc= 10 cents a foot :)
-
- hp7550a:br#9600:mx#0:lp=/dev/ttya:ff=:sd=/usr/spool/lpd/hp7550a:pc=1000

- if you want to print PostScript on it, you'd probably be better off
- selling it and buying a cheap dot matrix and using something like Dots.
-
- Printing bitmaps on a plotter would be quite an impressive thing to watch
- the plotter do, but the results would be a bit spotty.
-
- Converting PostScript to HP-GL (expecially the level the 7550A is running)
- would be quite a task, at best you might be able to get lines and text
- and maybe patterned fills to work if you were to write a full
- postscript interpetor that could do some sort of blasphemous PS->HP-GL
- transformation.
-
- If you want to use it with NeXT Apps and PostScript, my words are "sell it".
