| I've had mine for many years. Still works just fine (it's on its third
computer).
On the Amiga end:
I use the Okidata_92 printer driver that came with my 1.3 workbench.
Relevent lines from preferences are: 66 lines, Pitch 10-Pica,
Spacing 6 lpi. The graphic 1 menu is set to "black and white".
Actually, I don't usually have my preferences set for this because I
have a color Quadram Quadjet on the parallel port. The u92 is on the
serial port and I just output files directly to the serial port to print
them.
I have printed b+w pics on the u92 and they come out only ok.
The u92 can print dots at 60x72 or 72x72 dpi, depending on how
it's set up. I suspect that the driver does not set it for 72x72 dpi.
You could try setting it to 12 characters per inch before printing
graphics to see if that forced it to 72x72. (I'd try both the
preferences and brute force sending it ASCII code 28, decimal).
On the u92 end:
There's a switch pack inside on the front. (pop off the cover so that
you can see the ribbons. Then unscrew the two phillips head screws in
deep wells on the front right and left. Pull out the platen knob on
the right. Now tip the housing up and back 'till it comes off.
You will see switch pack near the linefeed key on the front panel.
On my printer, the switch pack is not labelled with ON and OFF, but
ON is to the left.

the serial line is an
extra option that you
probably don't have)
That's it for these settings, unless you have the serial line adapter and
plan to use it (in which case, let me know, life gets more interesting
when you play with the RS232 non-standard standard on anything).

You can make this printer do a lot (downline loadable character sets,
variable spacing between letters, super/subscripts, underlining,
etc. I made a file that shows off a lot of it, but it's on an
RT-11 format RX01 floppy and I don't feel like digging out the
computer that can read it (a PDT).
(in the following, <esc> stands for ASCII code 27, decimal
[30] stands for ASCII code 30, decimal)
The control codes that I find useful are
<esc>1 two pass "near letter quality", 40 ch per second
<esc>0 one pass, 160 ch per second (power up state)
I have two files, one with the first code, the other with the second,
and I print the appropriate one when I want to switch.
[30] 10 characters per inch (power up state)
[28] 12 characters per inch
[29] 17.1 characters per inch (for wide listings)
The major problem I have had using the u92 from my Amiga has been that
the u92 seems to power up with no tab settings. I could have a file
that sets them and dump that down before doing anything else, but
instead I wrote a little program that converts tabs to spaces, and
set up an alias so when I type "print" it runs the program, with its
output pointed at the serial line. If you want a copy, let me know.
Have fun

| Thanks! Sounds like out printers are slightly different because
mine is a parallel printer. What I could really use is documentation
on what switches are inside it and what the settings mean. Although
I haven't had time yet to look myself, the 1/3 "Software Enhancer"
manual gives some switch settings for it.
One of the pins in the printhead is slightly off center. I've tried
to correct this, but cannot. If someone comes across a printhead
for the u92 I'd be interested...

| The difference is that I purchased the serial card for the printer
'cause I had a DEC computer back then that only talked serial.
The serial option plugs in the back and adds some more switches
(which, since you don't have it, I won't go into).
The switches that I listed are the ones on the basic printer.
(the one's you've got). The info is straight from the manual.
If you need translations for any of the descriptions, just ask,
I believe I know what they all do.
Have fun
(hey, it's quieter than an LA50. ..a little)

| I'm at work just now (waiting for a compile and link) so I'm not near
any of my manuals.
When you say "the manual" I assume you are referring to an Amiga wkbench
doc. What switches do they list that I did not describe in .1?
(or which switches in .1 would you like described in more detail).
I don't think I made it clear that what I have is the standard parallel
printer, with a serial card added. The switches that I described are
the ones that are relevent to both parallel and serial. (The serial
card has more switches, and some jumpers. Gee, what you are missing
out on!).
