A PostScript error, offending command: mysetup can show up if you print to a QMS printer from FrameMaker 5.x for Windows (and maybe from other applications as well). The problem is caused by the QMS printer driver. This error is well documented on the Adobe web site.

Solutions
Download the latest SPD or PPD driver from the QMS web site or modify the ’setoutputray’ line of the QMS1725.SPD file to ’setoutputtray’.
