My understanding comes primarily from reading the 55's Native Mode
Spooler Reference Manual, especially chapter three, Configuring and
Operating Network Printers. There is a section, Creating and Using Setup
Files. If your vendor knows what they are saying, then they should at
the very least be able to tell you what their application expects (this
font, this orientation, these margins, etc.); they should also provide
some guidance for both the NPCONFIG and the setup file, and any file
equations or application settings to have their application print to the
LDEVs that your printers use. You might then have the joy of figuring
out from your printer manuals what are the Oki and Philips escape
sequences to do that your software vendor expects to have done. Or just
maybe they would be willing to help if they also got copies of the
resulting files.

Sounds like your vendor is referring files declared as the setup_file
globally and for the particular LDEV in the NPCONFIG.PUB.SYS
(these same files can also be used as an ENV file in the file equation
for the printer). If this is the issue, then you only need this if
everything printed to that printer needs some escape sequences to print
with certain settings for the entire document, such as settings for
landscape vs. portrait (if you need to change from the printer's
default), a single font, that sort of thing.

Where the ENV file approach becomes useful is if some documents use one
group of settings, but others differ. For instance, you might want to
print STDLists landscape with a compressed font, but other documents
portrait with, say, Courier. Then you would print to the different file
equations, which point to the same LDEV or class. But it does not sound
like your vendor is necessarily doing this.
