This document describes in detail how to write a plug-in converter module for use with the Download Manager under PrintingLib version 8.6 (included with LaserWriter 8 version 8.6) and later. It contains information about the pieces a plug-in must have, discussion of a sample plug-in and tips for plug-in developers. This Technote is directed at application developers who wish to write plug-in converters. The Printing Plug-ins Manager is intended to make it straightforward for software clients to create, load, and use shared libraries which can be treated as printing plug-ins. The Download Manager has been implemented using the Printing Plug-ins Manager to manage its plug-ins. Future printing software will use the Printing Plug-ins Manager to manage other plug-ins. This Technote is directed at application developers who wish to write plug-in modules. This Technote discusses the Download Manager API that Download Manager clients would use to call the Download Manager to cause a file, or other data, to be downloaded to a PostScript printer. (The Desktop Printing software is an example of a Download Manager client that uses this API.) Furthermore, this Technote examines the APIs that the Download Manager uses to call the low-level converters. This material is intended for the writers of the low-level converters which are called by the Download Manager. Updated
This Technote describes what changes need to be made in your application to support drivers that use extended print records in LaserWriter 8. Technotes |
