That is the way it works. For the session.
In some versions of pdox and OSes it hangs
for a long time or hangs forever, I have written a bunch of threads on this
(years ago). Though have not seen this in win10 paradox 9/10.

example
I read the current printer into a var, switch printer to pdf printer, print,
set printer back to what it was.
