Is it possible to block certain applications or certain things from printing to labels? The client is planning to use Zebra printers installed and configured as "just another printer", but they are concerned about users mistakenly sending an Excel document or something else to a Zebra printer and wasting labels. I was unable to find any other options from Zebra to print labels, as their operations team found security vulnerabilities with Browser Print, and they need offline support so the SendFileToPrint API was not an option either. We already have the label ZPL generated, but we're then converting that to an image (via api.labelary.com) and sending this image (embedded in an HTML page) to be printed. I'm not finding an obvious way to prevent other things from being printed. Is there anything I'm missing here?
