There is not any easy way, except to query for the name of the printer. As long as you don't change the name you can make some good assumptions about what kind of printer you have. If it comes back and says QMS-PS810, then you know certain things. You can also read the version of postscript in the machine. That will also allow you to determine status and info for the printer. To my knowlege, versions 38 and later can go all the way up to 57K baud, and some above. Cheers Woody

The above piece of code places the output on the printer itself. It is
a start, though not exactly what you are looking for.
