I have written several posts regarding Zebra printers and the problems they have had with labels that rotate when they shouldn’t.  I read that this was fixed in CR 2008 with a recent service pack, but it isn’t clear if this was fixed for CR XI.   I just learned that Seagull Scientific provides free printer drivers for many zebra printers (and others).  These do not seem to have the problems with rotation that have been described, so that is another potential solution for some of you.

Update 11/30/2024:

This came up recently with a customer who had installed these drivers to solve the problem.  Even then it didn’t work at first until he ‘recalibrated’ the printer to the media. Then the issue was resolved.  Just in case someone else has a similar issue he shared the steps for the Zebra GK420d desktop printer:
1) Holding the feed button down
2) Wait until it blinks once, then blinks twice in quick succession.
3) Immediately release the button
4) It will automatically print out a few labels or so to figure out the dimensions.

(and thanks to Samuel Lindemulder of Kentwood Powder Coat for sharing these steps.)
