I have worked with a similar Intermec Printer, I found it was acceptable to create a container on screen with the aspect ratio the same as label to use, then layout all the data as labels, text, values, barcodes as controls within the container and finally use ‘system.print.createPrintJob’ to create a print job to the printer to print the container.
This allowed a label image to be show in the ignition window of the exact label printed.
