I wonder if an Eqson compatible with serial port can be connected to an Apollo's RS232 port. It would be nice to have a fast line printer just for printing text without going to the Imagen or Versatec. Has anyone done this yet? Any comments from Apollo? Jinfu Chen Motorola

It's a serial laser printer with diablo 630, epson, HPGL and HP PCL emulation. To set it up, I had to make up a null-modem cable with pins 2-3 swapped, and with the hardware handshaking disabled by jumpering pins 4-5 and 6-8-20 on each side of the cable (an EE friend suggested this cable, I don't know why it works). It runs fine at 19200 baud, using XON/XOFF handshaking, IFF new line delay is set to zero (with the "tctl line 1 -nld 0" command). Otherwise, the printer stops talking to the Apollo (is this a bug?). I'm still at SR9.5. I also use this same port and cable to transfer files to my Mac II. All I do is start up siologin on /dev/sio1, log in with the Mac II in vt100 emulation mode, then transfer files using YMODEM at 19200 baud. Now for some questions of my own. I've never gotten the apollo print utilities prf and prsvr to work with my printer. I end up with partial files printing out, files stacking up in the queue, etc. I'd use lpr, but I also ran into the same problems as with prf. Does anyone have any suggestions? Right now, I'm using a Bourne shell script which initializes the /dev/sio1 port then executes a "cat $* >/dev/sio1" command. It works fine, but it's not a print spooler. Is there a printer driver for the Apollo print utilities for any of the following: 1) HP LaserJet+ 2) HPGL 3) Apple ImageWriter II Are any of these drivers public domain? Is there a filter which converts troff output to a form suitable for driving an HP LJ+ or Apple IW-II? Currently, I'm using nroff with an "mm" macro package I wrote to drive the laser printer in diablo 630 mode. It takes advantage of the proportional-spaced fonts, but I'd prefer to use troff if possible. Thanks in advance, Brian K.

I have hooked up an old DEC Letterwriter 100 to the DN330 in my office. I use the DOMAIN/IX BSD4.2 lpr facility to print to it so I don't have to fool with the device characteristics of the print server. Also, if you're using BSD4.2 TCP/IP, you can have BSD4.2 print jobs routed to a printer on a foreign host running TCP/IP and a Berkely-derived line printer daemon. For instance, the Letterwriter is available only from my DN330 by using lpr -Pletter, however the default printer is a DEC Decwriter IV connected to a Sun 3/260 that our Apollo ring is attached through Ethernet, and this is available from all nodes in our Apollo ring (running BSD4.2 TCP/IP). Look into the printcap file in your DOMAIN/IX Berkley manuals. Rob Gabbard UUNET: uunet!sdrc!crgabb Structural Dynamics Research Corporation "Why should I worry what happens tommorow ?

There are print servers for the HP Laserjet and the Apple Imagewriter I (not II) in the ADUS library. There are also plotter servers for the HP7475, HP 7550, and HP 7570 plotters in the library. These are HPGL devices, and the server spools files of HPGL commands to them. It does not, however, convert text files into HPGL for a printer. Most of these servers are written in Pascal and are easily adaptable to new printers. -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter@eddie.mit.edu mit-erl!mit-richter!krowitz@eddie.mit.edu mit-erl!mit-richter!krowitz@mit-eddie.arpa krowitz@mit-mc.arpa (in order of decreasing preference)

I don't believe there is an ascii printer type for prf yet, though. You can fix it three ways: 1) use the -transparent switch every time you print something, 2) make your own prf print driver, or 3) make your own lpr print driver (assuming you don't have an ascii one yet). -- --------------------------------- UUCP: {uunet, ihnp4!umn-cs}!hi-csc!giebelhaus ARPA: hi-csc!giebelhaus@umn-cs.arpa Nobody I know admits to sharing my opinions.
