OT: Help with printer setup strings

Using Clipper and FoxPro2.6a DOS w/ 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.

@0,0 say CHR(27) + '&l0o2a80p8D' + CHR(27) + 'a132M' + '(10U' +
CHR(27) + '(s0p16.67h8.5v0s0b0T'

But on the 8100, it somehow thinks the right margin stops at 80 and
the page
length is 66.

Can somebody please help me?

Thanks in advance.
