Sun Printcap file for HP XL300 Printer

In spite of suggestions from David Houlder and others I have not succeeded
in getting our HP XL300 to accept Postscript output from ps.map. I expect
that this has to do with the pleasures of the Sun Printcap file. When I
called HP, they had no information on what ought to be in the Printcap file.
I am running SunOS 4.1.3 and sending output out the serial port and through
a serial/parallel converter to the parallel port on the HP printer. I think
that if the correct serial parameters are in the printcap file, then the
converter should work. I set the dip switches on the HP to Postscript, since
we have the HP Postscript card. Here's what's in the printcap file so far:

#############################################
# entry for the HP XL300 color postscript printer
hpjet|lp2:\
  :lp=/dev/ttyb:\
  :sd=/var/spool/hpjet:\
  :lf=/var/spool/hpjet/log:\
  :mx#0:\
  :sf:\
  :sh:\
  :br#9600:\
  :ms=-parity,ixon:

I've checked all the permissions on the appropriate files and they're as Sun
suggests. I suspect the missing or incorrest parameters are the :ms
parameters. Anyone have ideas?
