If I use "set printer to name getprinter()" it works.
If I use "set printer to name 'HP LASERJET IIIP'" it works.

But, if I use:
lcPrinter = getprinter()
set printer to name lcPrinter
it doesn't work. Get error 1957 Error Accessing Printer Driver.

Is there no way to use a variable with the printer name for this command?
