We have 30 or more older Zebra printers in our plant that are model Z4M. New ones were ordered that are model ZM400 but it turns out that they are 300 DPI instead of 203 DPI like the old ones we have. The problem is that the old 203 DPI labels don't print correctly at the higher DPI(they are smaller). We can't change the label definitions because all of the old printers are still printing at 203 DPI.
There is a ZPL command in the manual that says:
"^MU also allows for printing at lower resolutions — 600 dpi printers are capable of printing at 300, 200, and 150 dpi; 300 dpi printers are capable of printing at 150 dpi."
Does this mean we are out of luck for printing our old 203 DPI labels with this printer? Is there anything we can do other than get different printers?
