We resolved this by instantiating another copy of the Library for each printer.

This is not a multi-threaded application, so the print function was returning before the next one started.  The document is being removed from the library before the next one starts printing.  And the printer is being specified by name.  So I'm not sure why the jobs would go to the wrong printer.

i think it should be only necessary to check if one printjob is finished before the next one starts?

Our application is printing to two printers.  One is for documents, and one is for labels that are supplied to us in PDF format (thermal label printer).

For the document printer we are using NewCustomPrinter, SetupCustomPrinter, and PrintOptions calls before calling PrintDocument passing in the name of the printer returned from NewCustomerPrinter.

For the label printer, we are calling PrintOptions, and PrintDocument passing the name (assigned in Windows) of the label printer.

Occasionally we are seeing the document and/or the label print to both printers at the same time.  Is there some kind of reset or clear that we need to be calling when switching printers?
