Fax Option for Win 95
At the present time NEC is not planning to offer updated PostScript Fax drivers for Windows 95.
Adobe Systems, the developer of the original PS Fax software has decided not to offer a Win95
compatible PS Fax driver. PostScript Fax was offered on NEC Silentwriter models 95, 97, and 1097.
All three models have been discontinued.
PCPanel for Win 95
Because of significant technical changes required to update the current PcPanel software for Win95,
as well as having limited resources, NEC Technologies, Inc. currently does not have plans to offer
updates to this Software.
QuickDraw GX Drivers Macintosh
Due to QDGX's limited acceptance in the Macintosh market and the amount of development effort
required to develope QDGX drivers for older model printers, NECTECH currently does not have plans
to offer QDGX drivers for older NEC printers. However it important to know that these printers can
function with the existing LaserWriter GX drivers which Apple ships with System 7.5.x. Apple ships an
extension called Desktop Print Monitor. This ships with 7.5.2 operating system and Apples 8.3 driver
and supports drag and drop, and True Type GX fonts.
