How do I stop my printer from skipping a blank row of labels in between each row I print?

I was using LibreOffice Writer to print terminal block labels on my TDP43MY and was having all kinds of problems. (I tried EasyMark too, but had just as many problems.) The printer was constantly switching landscape and portrait modes on me. It would print 2 sets of good labels (portrait) and then the next label would be landscape. It did this no matter if I printed one page at a time or if I printed the whole document. I spent over half a day trying to get it to work, and finally succeeded - read on.

No surprise that the Panduit TDP43MY printer is really a Zebra printer. I discovered this by accident when I first got the printer. I connected it without first installing the driver and windows asked for a driver for a Zebra printer. Knowing it was a Panduit, I rejected windows offer and installed the Panduit driver. I spent a whole day trying to get it to print correctly and decided I would try windows recommendation of a Zebra driver. I did some digging and discovered it is a Zebra TLP 3842 printer. I removed the Panduit driver and installed the Zebra TLP 3842 driver. The version I have says "Windows driver for ZDesigner TLP 3842 Version 5.1.07.6290 Copyright 2016". I then used LibreOffice Writer to print my labels again. Wonder of wonders it printed with ZERO problems! Yeah for Zebra!
