Here is two different ways to adjust the LW files to print to a file or, in the suggested way, to a serialport. You have to make sure you have the same version of Laserprep and LW driver as the machine you will be printing from, otherwise this won't work. ===+==+++==+++==++=+++++++++==++=++++==+=++==+==+++=====+++++++=++=++=++=== Info-Mac Digest Thu, 1 Feb 90 Volume 8 : Issue 20 Date: Mon, 29 Jan 90 13:47:40 PST From: Ray_Davison@cc.sfu.ca Subject: Serial line LaserWriter Awhile ago someone had a request for information on connecting a LaserWriter to the serial port through a switch box. I had a similar need. I have a Mac and a Unix box and wanted to use the printer on the Unix box from the Mac. I didn't want to spend the money for a Kinetics box for just one Mac so I went the route of using command-F to create a file, moving the file to Unix and using macps to print the file. This was rather tedious. I modified the LaserWriter driver as outlined below. The changes I made were specifically designed to print over a serial connection from the Mac to the Unix box, but may be useful to print to a serial connected LaserWriter. Changes to the LaserWriter driver (version 5.2) 1) Duplicate the file and give it a useful name. 2) Use ResEdit (or something similar) to make the following changes: - to simulate the pressing of command-F resource PDEF number 125 location from to -------- ---- -- B96 '57C0' '51C0' B9A '56C0' '50C0' BA2 '57C0' '50C0' BAA '57C1' '51C1' BB8 '57C1' '50C1' if you need the Laser Prep file (as for a serial connected printer) then you must simulate command-K (note: I haven't tried this). Do the changes above except: BA2 '57C0' '51C0' BAA '57C1' '50C1' - the following two changes prevent the creating of a file and the subsequent call to _SetEOF to empty it: resource PDEF number 125 location from to -------- ---- -- D96 '554F' '6038' 142C '660C' '600C' - change the string in resource STR number -8159 to something more useful than "Creating PostScript File" (e.g. I used "Sending print job to NeXT"). - set resource STR number -8191 to the name of the serial port you will use. ".BOut" for the printer port or ".AOut" for the modem port. A couple of notes: the default settings for the serial ports are 9600 baud no parity. So far this has worked fine but I may try changing the speed. When you choose the driver with the Chooser, it will turn on AppleTalk. If you are using the printer port then you *must* turn AppleTalk back off before using the modified driver. On the Unix end: I modified macps to "break" instead of "continue" when it finds the string "%%EOF" and then the command macps < /dev/ttyb | lpr can be installed in a deamon that loops forever (modify /dev/ttyb to use whatever serial port on your Unix box you connected the Mac to). I hope someone finds this useful. -------------------------------------------------------------- Info-Mac Digest Tue, 6 Feb 90 Volume 8 : Issue 24 Date: Sun, 4 Feb 90 00:12:26 PST From: Ray_Davison@cc.sfu.ca Subject: More on serial line LaserWriter A few issues back in Info-Mac, I gave a description of turning the LaserWriter driver into a serial port PostScript driver. Since then I have received a couple of messages, mostly asking for similar updates for the version 6.0 driver (are you people never satisfied :-) I also recieved a hint on doing one thing differently (see below). In light of that, I have applied the updates to version 6.0 of the driver, and present the new formula below: Resource PDEF number 125 (first always write to a "file") location From To v5.2 v6.0 B96 C78 '57C0' '51C0' B9A C7C '56C0' '50C0' BA2 C84 '57C0' '50C0' ('51C0' for Laser Prep) BAA C8C '57C1' '51C1' ('50C1' for Laser Prep) BB8 C9A '57C1' '50C1' (the hint on doing this part differently was to modify resource DITL number -8191 to make the "Disk File" box visible. The problem I had with this is that the box doesn't stay "ticked" between uses of the driver, so you have to retick the box each time. This didn't do me much good since I always want to send the print job to the serial port. If I am missing something, I hope someone will let me know.) (next don't create a file (still in resource PDEF/125)) location From To v5.2 v6.0 V5.2 V6.0 D96 E9E '554F' '558F' '6038' (next, don't do _SetEOF) location From To v5.2 v6.0 142C 1860 '660C' '600C' Resource STR number -8191 Change this from "PostScript" to ".BOut" for the printer port, or ".AOut" for the modem port. Resource STR number -8159 Change to a useful message instead of "Creating PostScript File". For example "Sending print job to Unix". Resource PAPA number -8192 Change the name of the printer if you want to. Ray Davison Simon Fraser University Ray_Davison@cc.sfu.ca ==+===+=====++++++++++======++++++==+====+==++===++==+++====+===++++=+++== The easiest way to do it is to get MyPageSetup from sumex, which can, among other useful things, put a check box in the Print dialog. That way you don't have another init to run. Mind that you have to have the LW selected in the chooser. You can then turn off AppleTalk.
