We have several of these units and they confuse me every time. I've watched countless videos of how to load the media, run calibrations, reset to factory defaults, etc. I've used the Zebra Utilities to try and set them up differently. Periodically, one just stops calibrating or printing correctly and I spend hours trying to get it to calibrate. Sometimes, it prints in the wrong spot by a couple inches. Since a lot of people use these, the simple answer is that it is me. I'm not sure what to do, really. I don't think it's the printer as we have three of them and I have issues with every single one.
I'm open to any suggestions, even starting at ground zero. Oh, and we're connected via parallel port.
