Desktop Printer Utility: Printing PICT Files to PostScript Translator DTPs

I receive a warning when printing PICT files to a PostScript Translator Desktop Printer after printing to a different printer. Why is this?
When printing PICT files to a PostScript Translator Desktop Printer, we recommend you wait until the file has completed translation prior to printing to other types of printers, AppleTalk or LPR Desktop Printers for instance. If you print a PICT file to a PostScript Translator then immediately attempt to print to other Desktop Printers, your Macintosh may hang or freeze and display system errors of type 8 or -49. Your Macintosh may hang again upon restart unless you immediately remove the print jobs from the Desktop Printers. Restarting with Extensions off, so that Desktop Printers is disabled, will give you more time to remove the files.

PostScript Translator Desktop Printers may be created with the Desktop Printer Utility on Macintosh computers running System 7.6.1 and Mac OS 8.1 or later. Files you print are converted to PostScript file format and placed in a folder that you specify.
