HP printer emulation - 3rd try is a charm, eh?

In looking back through the archives I've posted about this twice before but
still can't get the printing to look right. I have a 170 running V5R2 and
an HP Laserjet 6P connected via a PC and emulating a 3812. Prior to today I
couldn't figure out what was meant by using PDT. I tried that and it's
better in some respects and worse in others.

If I print a program listing using option 6 in PDM the print looks fine. If
I compile the program and print the listing the print looks smaller but
still proportional.

I have also set it up using PDT. If I change the CA session settings
through "FILE - PRINTER SETUP", select "Use PDT", and click "SELECT PDT" I
can select "HPLJ4.PDT" (there isn't one for HPLJ6P but other posts indicate
a 6P emulates a 4 anyway). The print is larger and bolder but vertically
not proportional, with each line stacked right on top of the next.

On the AS400 side I've looked at the device configuration. If I were to try
to change the font identifier or point size it would just be a shot in the
dark. Is there a table somewhere that shows the fonts for the different
codes and point sizes?

This worked really well when connected to my old 9406-600 V5R2 so I'm not
sure what is different. If anyone can offer any help I would appreciate
it. TIA.
