I have a number of Zebra QLn220, QLn320, and QLn420 label printers to which I print from a FileMaker robot setup. Users print on FileMaker Go which creates print records, and then a bot on a single computer prints those records every few seconds to the specified printers For most of the printers it works fine, but for a few printers, FileMaker will go thru all the motions with no error message, except the print job never gets added to the printer queue. I've tested printing from Windows print settings, and a sample print job goes thru fine, so it's an issue of the job never actually getting created by FileMaker and added to the queue. Any ideas what may cause this?
I've attempted uninstalling and reinstalling the printers and creating new lines in the FileMaker script, but still no success.
