ISSUE: Every other label prints blank. 

 

Could be a “backfeed” issue:  before it prints it sucks the label in, so when it’s done printing the label is exactly at the perforation for tearing off printed labels.

 The setting shown below does not exist on every printer so you have to fix it in Label Matrix: right click on the label, Printer tab, Setup button: change Backfeed and test. Sorry I did not document what the code in the text file was....
