hp plotter

[David Fitzgerald]

i am trying to connect a hp plotter  7475A to my sun 3/60 and run it
through a printer daemon on /dev/ttya i.e.  lpr <plotter_file>

the plotter file is straight ascii text file and i have no problems
plotting about one page of commands. however the plotters error light
flashes through the entire process and aborts after a small portion of a
larger file. i believe the problem lies with the printcap entry but i
could be wrong.

here is my printcap entry: 
hpp:\
        :lp=/dev/ttya:sd=/usr/spool/hpp:\
        :br#9600:fc#0177777:fs#0177413:tr=\f:

i would appreciate any information regarding the correct printcap entry or
other aspect of the hp plotter that i should know about.


thanks in advance
