I'm trying to print a graphic image on a Z4MPlus printer. I uploaded an image on Generate Zebra ZPL from Image and downloaded the resulting zpl code, but when I print the image using notepad, I get lines going through it that look like a microscopic EKG. The printer is defined with a generic-text driver, something we have always used to print basic text and bar codes, but now we have a requirement for images. Here's the code I'm using (attached). I'm new to this and any advice will be helpful.
