In order to get 66 lines per page, you can modify the printer
filter to emit the HP control sequences to change the vertical
motion index.  We use these in our System V printer filter at
the beginning of every print job:

echo "\033E\c"                      # Reset printer
echo "\033&l66P\c"                  # Page length of 66 lines
echo "\033&l2E\c"                   # Top margin of 2 lines
echo "\033&l7.6C\c"                 # Vertical motion index of 7.6
echo "\033&l66F\c"                  # Text length of 66 lines

[ Note: for example, the last one means:
	ESC&l66F (no carriage return) ]

Once you've done this, any software using 66 lines per page will
work transparently.  The only drawback is that the lines are
a little closer together than on a printer that can print on
ALL of the page.  The Laser won't go within about a half inch
of the top or bottom.

Similarly, when you are running landscape mode, you can use the
same escape sequence, except that the VMI should be somewhat
smaller (see the manual) for the shorter "length".  We print
"line-printer" like images using a 16 pitch font on a HP
cartridge that gives us 176 (or so) characters horizontally and
66 vertically.

Regarding another posting: I have the beginnings of a troff to
HP filter.  It works okay as long as you don't:
	1) Change page length
	2) Use fancy characters not in the HP
	3) Try to change font sizes.  (it attempts to enforce 10/inch)
Has anybody got some font files (we don't got Berkeley fonts even
tho we are running 4.2) that we could use in this?
Anybody interested in this software?
