Filter Printing by Location

[mgobat]

Can it also made it possible to add an extra filter to this daemon to select only those requests with a certain location?
In fact, this can be a search for a string in the body of the mail.

"Why?
The building for our book storage has 3 levels (I1, I2 and I3) and every level has its own printer for the print request.
By making the print daemon to do the selection, you can fine-tune printouts.
At this moment this is done by outlook. Rules are looking for a string in the body and forward the mail to another mail address that prints the request.
As a result, you have always unwanted extra header information coming from outlook.
The print daemon just prints the body of the mail. And that is what you want, nothing more."
