We don't know of a product that lets you do this. For non-PostScript
printers connected to a VAX via RS-232, you normally have to save the file as
text only, and send this file to the VAX queue, using the device name of the
printer captured by that queue.
If you have DECnet support on the Macintosh, you can use the DECnet COPY
command to copy the file to the VAX, using the VAX node name and printer device
name as the destination (for example, ENGVAX::LPA0:, where "ENGVAX" is the
DECnet node name of the VAX, and "LPA0:" is the printer name).
If you don't have DECnet on the Macintosh, you have to transfer the file to the
VAX first, using a terminal emulation program and XModem or Kermit, and use a
VAX/VMS DCL command to print the file.
