Are your printer drivers installed locally or via "Point'n'Print"?
Are you using the native Windows drivers from the vendor or are you
using the CUPS or Adobe PostScript drivers (and let CUPS convert the
PS for you)?

OK -- this seems to indicate that you are using the native drivers
for Windows provided by the vendor, just as you did on your NT print

What do you mean... "fails"??
--> Does printing fail altogether?
--> Or is it just not printing in landscape mode?
If it is the latter, and if you are using a PostScript driver on the
Windows clients, check out the Release Notes for CUPS:
I seem to remember that there was a "landscape/portrait" bugfix in the
latest 1.1.20 release...
Also, printing from Excel is sucking. Are you sure you had the correct

Not necessarily. These things happen in Windows-only places also....

Yes -- user error, driver bug.... Did it for sure work (using the same
driver settings) with the previous NT print server?

Why should it? If you send ASCII text, with no "page advance" command
at the end, the printer wouldn't know that you want the page advance....

It does what you tell it. You don't tell it that there is a page
advance needed. You should send an appropriate Escape code to the
dot matrix printer.

Yes. For a first insight see the CUPS documentation about writing
filters.(*) (If it is too much work for you, you could go to the new
"printing consultant's" page at
where you can buy some support. (If our company does it, 10% go to
Linuxprinting.org as sponsorship money).
(*) You need a filter for the dot-matrix which just adds the page
advance command to any ASCII text file. It can also be done via
an "interface script". See "man lpadmin" and the "-i" paramter....
