I get the same error message if I set it to Persistent:no.
I probably always got that message, but I didn't see it until I put a Pause in the bat file.
I got Q&A to print to the USB printer! I had to change the share name for the eth printer first, then change the share name of the USB printer to what the eth name had been. I had a little trouble printing to it from Sesame so I hooked it back up to the eth and I had change the share names back again and I still had to reboot before it would print to the eth again. I'll leave it like this for now until I can get a long enough USB cable to have both connected simultaneously. Then I will work on tweaking it. At least now I know it can be done.

fwiw, one of our attached network printers is an HP OfficeJet 6300 all-in-one, and our accounting software takes FOREVER to print to it if the file is large (about 20 times as long to print to that printer versus a very old HP Series II laser printer that is also attached to a pocket print server).  I'm testing 'today' if changing that printer will speed up my posting times on customers with large amounts of data.  Will report on results.

Update:  the 'slow' issue had nothing to do with software or OS or printers.  It was a network cable gone bad.

Hello magicfish,

One thing you can try is the SBasic commands NewDocument() and FinishDocument() so that the invoices are sent to the Printer as one 50 page document rather than 50 one page documents.

In GlobalCode add

NewDocument(1) 

Then at the very bottom of your printing code add the following

If @ResultSetTotal() = @ResultSetCurrentPosition() Then
{
	FinishDocument()
}
