I am encountering a variety of problems when trying to print separate documents concurrently to different printers in separate threads. Is this supposed to work in v7 (with Delphi XE)? If not, should it work in v8 (we have not upgraded this app yet). And if still not, then should it be sufficient just to put the qp.PrintDocument inside a critical section, or would I need to do the whole create-load-print-free one at a time?

Hi!

As far as i know QP isn't threadsafe.
So check the returning value before running the next printerjob.
Other opinions?

Cheers, Ingo
