I thought thats what postscript was. Ideally one would simply open the printer, redraw one's window (but now the drawing is done on the printer), close the printer, and the printer driver would know what needs to be done. The problem with Postscript is that one has to draw the data differently on the printer than one draws it on the screen. One Unix way to deal with this has been to use DisplayPostscript to draw the display. This didn't work terribly well mostly due to lack of speed. What Apple says they are doing for MacOS X is to use PDF as their core display technology. PDF is to replace PICT. For those who forgot, Apple aquired NeXT, whose Unix used DisplayPostscript. Much of MacOS 8.x and 9.x, and MacOS X (10.0) is coming from NeXT and ex-NeXT employees. Apparently PDF is to replace Postscript at Apple. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
