T/Maker has produced a series of ClickArt libraries that are bundled with a utility program called ClickArt Image Exporter. In order to create a file from these libraries that can be imported or placed into another document, you must use the ClickArt Image Exporter to convert the ClickArt file into an EPSF, PICT or AI (Adobe Illustrator '88) file. Any EPSF file created with the ClickArt Image Exporter and placed in a MacDraw Pro document will not print to a LaserWriter. When attempting to print this document to a LaserWriter with background printing active, Print Monitor will inform you that a Postscript error has occurred. The error is, 'undefinedresult', and the offending command is, 'itransform'. When printing without background printing active, the activity window will display the alert, 'A Postscript error has occurred: The error is, 'undefinedresult''. Canceling the printing at this point will prompt another alert from MacDraw Pro, "Sorry, the printer was unable to print some objects."
Workaround
Place the EPSF file into a new MacDraw Pro document. Save this document as an EPSF file. Import this new EPSF file into your original document. This will print.
T/Maker is aware of the issue.
