Offending command: md

A PostScript error ‘undefined’, offending command ‘md’, can occur when downloading Macintosh generated PostScript files to a RIP. It indicates that some required PostScript code has not been included by the Macintosh driver. The PSPrinter driver uses the dictionary ‘md’ for storing its privately defined procedures.


  • Recreate the PostScript file to solve the problem.
  • Try using a different PostScript driver.
