Actually, it very well could be a driver issue so the first thing to check is that you have the most up to date driver downloaded and installed.
But some drivers simply don't "play well" with FileMaker and the Mac version of this driver may be one such printer driver.
Well, Zebras are not supported on Apple products. So there is only one available driver which you don't download but just pull from the Apple catalog. I don't think I'm the only Apple dude trying to print on a Zebra, so I'm sure there is a workaround.
Problem Solved. I was using a printing template but not a label template. Apparently FM needs it to be a label template to translate correctly. I just created a new template but using the "label" option on the template creator. Voila! Thank you guys.
