You might be exceeding some limit.  Try sending ehandler.ps (available
from the adobe file server or many other places) in front of the file.
The printer should produce a page with some error message for you.

First of all, are you using VMS, Ultrix, or UNIX to print? Each of these
environments provides different mechanisms for error handling. For example,
in Ultrix (and some Unices), you need to use -Mkeep to get errors reported
as mail messages.

As to the actual problem, here are four possibilities:

    1.) Wrong fonts: The LPS20 uses the "DEC 29" fonts, while the others
        you mentioned use the "standard 35"> If there is interest, I can
        post font lists for you.

    2.) Use of the cexec operator. The other printers are 68000-based and
        support the cexec operator, which may be used on Macintosh systems
        to download image- or font-smoothing code or a TrueType rasterizer.
        This code is 68000 assembler, and will obviously not work on the
        VAX-based LPS20, or any other non-68000 controller. It also would
        fail on Level 2 printers.

    3.) Reliance on device-specific operators. This unfortunately includes
        a small number of fairly basic operators, like "letter". Again, you
        might succeed on a number of printers, and fail on a bunch of
others.

    4.) Implementation limits. Depending on the environment, some of the
stacks
        and VM are used up by the Symbionts, Translators, etc. This could
lead
        to VMlimit, Stackoverflow, or other errors.

If you still need help, please post more error info, either by using an
error
handler or by capturing the error messages from the printer.
