Printer Selection

[Guest]

Greetings Time Travelers. . . Sorry wrong group. And now for something
completely on topic.

I have an Excel app that must print to an impact printer. This printer is
not the default printer. I would like to have Excel do the work in selecting
this specific printer when the app runs. Of course it should return the
previously selected default printer as such.

For this to work effortlessly, a check for a specific printer would need to
be made. If it does not exist print nothing and exit. This is not a networked
printer (yet) and can not be easily selected if it is not already installed.

Your help in developing code to check for and select a specific printer is
greatly appreciated.
