You should not be calling PrPicFile, because the Personal LaserWriter does "draft" printing as opposed to "spooled" printing. PrPicFile should only be called for spooled printing. You can tell which type of printing is to be used by looking at the bJDocLoop field of the prJob field of the print record. Inside Mac, v. II, p. 155 shows an example in Pascal. Note that the Postscript LaserWriters do not complain if you call PrPicFile. You can get away with calling it and ignoring the error in the case of the Personal LaserWriter, but then you are printer-dependent since you cannot ignore the error if the printer is an ImageWriter. The right algorithm for all Apple printer drivers is the one given in Inside Mac. David Casseres Exclaimer: Hey!
