LaserJet 8100DN with DOS application

Archived from groups: comp.periphs.printers (More info?)

Using FoxPro 2.6a DOS on a LJ 8100DN - having trouble getting the page
to print in portrait mode, 80 rows by 132 columns. On my old LaserJet
II, I would issue the following command and it would work just fine.
But on the 8100, it thinks the right margin stops at 80 and the page
length is 66. Here's what I've been using:

??? CHR(27)+'&l0o8D'+CHR(27)+'(10U'+CHR(27)+'(s0p16.67h8.5v0s0b0T'

Can somebody please help me?

Thanks in advance.
