Subject: printcap entry for an Apple ImagerWriter II
The title says what I would like to get. I have this printer
collecting dust in a corner right now and I was thinking of hooking it
up to a sparcstation IPC.
Do I need to change the jumpers inside the sparc to make one of the
serial ports behave as a plain RS-232 port?
On the Imagewriter there is one dip switch which controls hardware
flow control vs. software (xon/xoff) flow control. Can I use hardware
flow control, provided that I use a connecting cable that has all the
necessary signals (I can think of pins 1 2 3 4 5 6 7 8 20: I am
missing anything?)?
Should I not even try this? Ie, is is worth it?
Thanks for all your replies and I will summarize.
What follows are the replies I got:

I've run them from a 2/120 and a 3/180. Here's some information:

I've used my Imagewriter on a UNIX machine. All you have to do
is flip the flow control switch. For reference, here is the list
of DIP switch settings (plagiarized from the Imagewriter reference
card):
SW1-1 SW1-2 SW1-3 Language
open open open American
open open closed German
open closed open American
open closed closed French
closed open open Italian
closed open closed Swedish
closed closed open British
closed closed closed Spanish
SW1-4 Page Length
open 66 lines
closed 72 lines
SW1-5 8th-bit
open Recognizes 8th data bit
closed Ignores 8th data bit, allowing
reception of "high" ASCII as from
Applesoft BASIC
SW1-6 SW1-7 Type Style at Powerup
open open Pica (10 cpi)
open closed Ultracondensed (17 cpi)
closed open Elite (12 cpi)
closed closed Elite Proportional (144 dots per inch)
SW1-8 Line Feed
open Not added after carriage return
closed Added after carriage return
SW2-1 SW2-2 Baud Rate
open open 300
closed open 1200
open closed 2400
closed closed 9600
SW2-3 Flow Control
open Data Terminal Ready (hardware handshake)
closed XON/XOFF (software handshake)
SW2-4
(not used)
If you have this hooked up to a UNIX system, your best bet is probably:
SW1-1 open American language symbols
2 open
3 open
4 open 66 lines per page
5 open recognize 8th data bit
6 open 10 cpi
7 open
8 open no line feed after carriage return
(I don't know whether SunOS is
more like SYSV or BSD. If the
former, make sure the port has
icanon and onlcr are set. If BSD,
make sure cooked is set.)
SW2-1 closed 9600 baud
2 closed
3 closed XON/XOFF handshake
Hope this helps!

One approach that eliminates screwing around with the sparc's serial ports would
be to get a parallel to serial converter box (pretty cheap) from a computer
store or from Black Box (try 800 information).
This would allow you to use an off the shelf PC style parallel printer
cable to the 'box' and an off the shelf mac to 25pin cable from the
box to printer.
After that you'll have the fun job of figuring out the appropriate way
to print text files to the printer.
A more fun project would be to get the NeWS PostScript rasterizer to gen
up 144 dpi images and write a little program to send them out to the printer.
This would be slow but would allow you to print all kinds of OpenWindow
stuff.
Gee, that would be cool, wouldn't it?

Leo,
Don't touch anything in the IPC. Use the supplied serial adapter (DIN to D25) plus a null-modem cable.
Set your baud rate, parity, flow control and other goodies in your printcap file. Read the "System & Network Administration" manual. Its instructions are
pretty complete. It refers you to stty for "ms" parameter specs.
Read these carefully as printcap entries sent to you often need a little tweaking.
Good luck.
Steve
PS: Sorry, I don't have your printcap.

If you want to use hardware handshake, you have to specify hardware
handshake in your printcap file. It is not enough to set hardware
handshake in the EEPROM. lpd seems to reset the port completely...
