[net.micro] matrix printer query results

edler (02/04/83)

Several weeks ago I posted a query on dot-matrix printers with
(I think) the following characteristics:

	under $1000
	"reasonable" print quality
	wide (~15 in.) platten
	tractor and friction feed
	bit graphics (complete control on the dots)
	serial rs232 interface

Well, I figured I should follow up, so here it is.  Any further
info would be appreciated.  I haven't really made a decision yet.
Thanks to those who responded with the following information.

	We have several C.Itoh 8510/ACD printers and are very happy with
them.  Features include:

	* 120 cps bidirectional print with full head motion logic
	* Graphics mode with 160 dots/inch horizontal by 144 dots/inch
	  vertical.
	* Built in fonts are: pica, elite, compressed, proportional,
	  double wide, Greek and graphic.
	* Bold and underline capabilities
	* RS-232 serial interface with 3K buffer.  Understands XON/XOFF,
	  and DTR flow control.  Runs at line speeds up to 9600 baud.
	* Friction and tractor feeds. Can use single sheet feed, roll
	  paper, fanfold or multipart forms.
	* Fairly small and unobtrusive.  Rather spartan front panel
	  with controls for select, line-feed and page eject, and
	  indicator lights for power-on, select and out-of-paper.
	* Price: $600 mail order, slightly higher from local distributors.

	We've put together a nroff terminal description so we can use
the proportional font and output document draft.

	The 8510 has an 8" carriage, but the C.Itoh Prowriter 1550 is exactly
the same printer with 15.5" carriage instead (for about $150 more than the
8150).  If you just want to have 132 column output, the 8510's compressed
font gives you 136 columns on 8" paper, and it's very readable.
-------------------

I've heard nothing but good things about the Epson MX100 - around $700
with F/T fitted.
-------------------

We use the OKIData MicroLine 84 printer which meets your requirements except it
may be $150-200 over your $1K limit.  It prints at 200cps in correspondence
quality mode and 50cps in "near letter quality" (their terminology) mode.  The
RS232 interface includes a 2K buffer (smaller ones were available in past so
be careful in specs for purchase).  Without the RS232 interface (i.e. Centronicsonly) it is under $1K.  Seems well built and maintenance manual is available for$35.  Have also used IDS Prism but don't know if it is available with wide
platen.
-------------------

I just bought a dot matrix printer, a C.Itoh Prowriter.  I am very
happy with it.  I researched printers quite a bit before buying it.
The only one I wasn't able to look at was the IDS Microprism.
Prowriter is an upgrade of the NEC 8023, as follows:
	120 cps logic seeking bidirectional
	integral tractor and friction feed
	many character attributes:
		5x7 characters with true descenders in a 7x9 box
		pica(80 cols), elite(96), compressed(136) pitches
		all pitches can be elongated
		proportional spaced printing with microjustification
		underline and boldface attributes
	decent graphics:
		one pass: 72v x 160h (dots per inch)
		two pass: 144v x 160h
		horizontal movement between dots of 160 dpi
			(print 8 bits vertically at a time)
		vertical movement of N/144 where 0<N<100
			(adjustable from line to line)
	centronics parallel standard, serial optional
	one year(!!) warrantee from distributor (Leading Edge)
	10" or 15" carriage width, using same inexpensive ribbon
					(price an mx100 ribbon!)
	selected as next standard printer for Apple
	low cost: I bought mine(10") for $425 plus $8 shipping
			(check ads in BYTE for best prices)

Am I happy?  Of course not.  Okidata just announced the
Microline 92.  160 cps plus correspondence quality at 40cps.
Loadable character sets.  Lists for $699.  (Discounts likely.)
Sigh!  You can't win.
-------------------

The Okidata 84 is an excellant printer, high quality construction, etc.
and very fast (200 cps). The only marginal qualification from your list
is price--wholesale is about $1000. Oki is coming out with a new model
(#93, I think) around April which is as good as the 84, but only goes
160cps and probable will cost about $800. As a bonus on these, you get
a letter-quality mode (two passes). On the #84, this is 50 cps.
-------------------

Get the Okidata 84a (at $799 in some ads) Not only does it have everything
you specified it is A.) Faster B.) More reliable.

I have found that as wonderful as an Epson is for the money, it is
essentially light duty printer. I found that after printing a couple
of images on it it quickly overheats and shuts off. (Granted in text
mode it will work for several hours before over heating) The Okidata
on the other hand runs 1.5 times as fast and has NEVER over heated or
been "down" for reasons of over use. Additionally, it may be cheaper
than the MX-100 but you'll have to check that one.
-------------------

We have both the Epson MX-80 and the C.ITOH 8510A printers
In my opinion the 8510A is the better of the two, the print
rate is much faster (120cps) and in general is better built.
The price of the C.ITOH printer is 645.00, which includes both
traction and friction feed. It has all of the features you
are looking for, also it works well with Televideo Terminals.
If you are also looking for a good terminal the Televideo is
the best buy around. The printers serial interface baud rate
is selectable up to 9600. The unit comes with a 3k buffer.
