Does ZebraDesigner use the Zebra SDK to print?

Hey everyone,

I'm having an issue with our LP 2844-Z printer failing and needing a manual recalibration after someone turns it off while it's printing using my program but it has no problems when powered off mid printing when using ZebraDesigner. Does anyone know if ZebraDesigner uses the Zebra SDK or a different method for printing? I also noticed that there is no spooler print log when using my program but there is when using ZebraDesigner.

I did grab a copy of what ZebraDesigner prints and I used that ZPL in my program with the same results so I'm thinkign ZebraDesigner prints a different way than I am, unless it sends two sets of commands to the printer and I'm only capturing the second set.

Anyone know?
