Has anyone managed to get a serial-line attached Apple Laserwriter to print from an RS/6000? I have the device set up properly (ie I can echo postscript commands to /dev/lp0 and it works), and I even got a postscript file to print using this crazy AIX printing. The problem comes when trying to print ASCII files. What is the proper formatter/input filter to translate ASCII to postscript? Has anyone modified one of the predefined printers to successfully work? Thanks for any help.

I havent done this, but a place to start is to configure the laserwriter as a 4216-031, which is also a Postscript printer that supports HP, Diablo, and IBM PC emulation. When you configure the virtual printer for this device, you are given options to configure queues for Postscript, HP, Diablo, and ascii. My understanding is that the backend does not translate from these streams, but instead, sends a prep string (in Postscript no doubt) that kicks the printer into the proper emulation mode. Since the Laserwriter has these same emulation modes, the technique of mode switching is probably the same, but the details of the data sequence to do the switching is probably different. Perhaps your printer manual tells you how to do this (other than setting hardware switches) and I suspect you will have to understand Postscript language to make it happen. ********************************************************************* IBM AIX Porting Center | RSCS: CHUKRAN at AUSTIN 11400 Burnet Rd. | AWDnet: rudy@chukran.austin.ibm.com Internal ZIP 2830 | internet: chukran@austin.iinus1.ibm.com Austin, Texas 78758 | Voice: 512-838-4674 Tieline: 678-4674 *********************************************************************
