I am currently using a ZEBRA QLn420 to print lables from the iForm application.  I need more printers to delploy throughout our work environment but I don't need the expensive mobile printers.  I purchased a Zebra ZD420 bluetooth that uses ZPL as required but it will not print the variable data in the form...only the static text.  I have worked with both iForm and Zebra tech support but do not have a solution.  Can anyone share with me if you have had success with other models of Zebra printers besides their mobile line?
