These problems are related to a known issue with some applications that do not follow the Print Manager guidelines, more specifically, with the PrJobMerge call. Print jobs not being printed are being faxed to the last person you sent a fax.
The LaserWriter driver v8.2 resolves many instances with it's "non-sticky" destination field, however, there are still some cases where applications cause the problem, not the driver. It is the application's responsibility to set the correct printing destination for each of the documents. This is performed using the Print Manager call "PrJobMerge". PrJobMerge is a print routine that applies information specified by a user in the Print dialog, to all documents selected from the Finder. Our guess is that the application is not using, or incorrectly using, PrJobMerge.
A new version of the LaserWriter 8.2 printer driver will be posted shortly to online services. The new version is LaserWriter 8.2.2. Howerver, this is an application-related issue which the driver is working around.
