My thanks to everyone who sent me help and instructions on connecting our LaserWriter and 3Server. Background: We have a 3Server3 (3S/201) running 3+Share. We connected a LaserWriter IINT with 4-wire serial cable. We had problems with long print jobs producing PostScript errors and with the server sending only 7-bit data. 1. When using 3Ins to add a LaserWriter as a network printer, you have to use the Hardware and XON/XOFF Combination protocol (choice 4). If XON/XOFF alone is selected, only 7-bit data is sent by the server. (And so you lose the top half of your character set.) 2. There is a way to get enough hardware handshaking out of four-wire cable to make both the server and the printer happy: On the server side the pins are 2, 3, 5-6, and 7. On the printer side the pins are 2, 3, 7, and 20. They are connected 2-3, 2-3, 7-7, and 5&6-20. 3. In the 3Plus\3Share directory there is a laser prep file called LWPREP. This file is sent by the server before the first print job. (If the printer was shut off, then turned back on, this file is sent with the next print job.) The opening lines of this file contain some postscript code that sets the printer to hardware handshaking (and no parity). If you want your printer to be set up some other way, you must change this file or the server will undo your changes the next time the printer is shut off. There is a very handy piece of postscript code in the IINT manual that will print out the printer's baud, parity, handshaking, data bits, and stop bits setup. Again, thank you all for your help! -- -- Sue -- ========================================================================= Sue Klefstad Ill. Natural History Survey klefstad@uiuc.edu
