SOURCE: Print Width Issue

the issue you are having is DPI related, when data is sent to the printer and rendered it is dot for dot, so a Z4M 203dpi printer has about 800dots on the printhead where your printer has about 1200dots on the printhead. so when your software prints to dot800 thinking it is the edge of the label it is infact at 60%. there sould be an option in the software to configure around this. if not the is an option in the printer to convert DPI setting ie 150>300 or 100>200 and so on. but i don't thing you can make a 300dpi print as 203dpi


best of luck

This printer requires special software to print labels with. It uses a unique PCL language to work with. Thats why when you use these printers with Fedex or UPS software, it typically downloads forms first before working.

Zebra used to see a label designer program to work with it. You might want to check with them to see if they still carry it.

SOURCE: prints out 2 labels at once

I've seen this be due to dirty sensor or misconfigured media setting.  Clean the sensor in the middle of the edge on the inside and outside of the printer, then if still having trouble - Inside the printer it should tell you that if you are having printing trouble:

1. turn off the printer
2. Hold down the feed button
3. turn on the printer and at the third red flash release the feed button
4. it will then feed some pages print some info and ask you to hit feed again to exit dump
5. hit feed again and it will say exiting dump
