Introduction

Congratulations

for selecting

this Radio

Shack computer product! The DMP-200

is a

high-density

dot-matrix

printer

which

can perform a

variety

of different printing

operations.

For

instance,

it can

print:

•

Proportional

spaced

characters.

•

Monospaced

characters

(Normal,

Condensed and Compressed).

•

Correspondence

Quality

characters.

•

Graphic

characters.

For maximum efficiency

, the DMP-200 operates

in

three modes:

•

Data

Processing

Mode for fastest

output

of program listings or data.

•

Word

Processing

Mode

for letter-writing

or the creation of any text documentation

.

•

GraphicsMode

for drawing

pictures, figures,

or

graphs.

For word-processing,

you'll

find the

DMP-200's Proportional

spaced

characters (created

on

a variable

15x9 dot-matrix) can

produce letter-quality

results.

If,

however,

you need

a print-out that

is produced

faster, Monospaced characters (created

on

an

9

x

8

dot-matrix)

are just the thing for you!

In

the Graphics

Mode,

you can use graphic data

to

draw

just

about

any

type

of

graphic

configuration

you

desire.

You can

use

three

types of paper

with

the DMP-200.

•

Standard

(4"-

10"

wide)

computer

fanfold

forms

with

guide

holes. The Printer

can also

print

one original

and up to two

carbon-copies

.

•

Standard

single-sheet

typewriter

paper for

use

as an ordinary

typewriter.

•

Roll

paper

(8

Vi

wide) with

a

1"

core and

a

maximum diameter

of

5".

Other

software-controlled

features include:

•

Bi-directional

logic-seeking

carriage motion,

(uni-directional

in Graphic Mode.)

•

Full-

or

Half-Line

Forward

and

Reverse

(for printing

above

or below the

*

'current'

'

line)

and 3/4 Line

Feed.

•

Underline

capability.

•

Paper

Empty

sensor

automatically

stops the printer so you can replenish the paper.

•

Parallel

and

Serial

Interfaces.

and much

more

!

2/ Setting

Up

the

DMP-200

This

section

will show

you how

to

set

up the DMP-200 so

you can

begin using it as quickly

as

possible. This includes:

•

Loading paper.

•

Replacing

a ribbon.

•

Connecting the

DMP-200 to a TRS-80

and

more!

The following

Start-Up

Checklist

is a

summary

of

how to

set up your Printer. You

should

follow

this

procedure every

time you start-up the

Printer —not just the

first time.

Find a good spot for

your Printer. Be sure to

consider:

•

The Printer

should be placed on a sturdy work surface.

•

The length of the printer

cable

will determine how far from the TRS-80 you can

place

the

Printer.

•

Papertakes up

space.

Be

sure to

leave enough room forsmooth paper

flow.

•

Don't place the Printer near noise generators such

as

refrigerators and

industrial

equipment.

Be sure the

POWER

switch

(at left side of Printer) is OFF.

Remove

the

Top Cover

and the packing materials.

Install

continuous

form fanfold paper,

single-sheet

paper,

or

roll

paper.

Refer to

Paper

Loading.

Check the Ribbon

Cassette. If it has not been installed, see Ribbon

Installation/Replacement.

Connect

the AC

power

plug to a 3-wire,

(220/240v,

50 Hz where the

unit

is so marked).

Check that the

Printer

is

ready

by running the Self-Test.

Connect

the

Tractor

Installation

and

Removal

This

printer

can

be

used

with

either the

Tractor

Feed system or the Friction Feed

system.

The

difference

is

that

the

Tractor Feed

system

is

used with

paper

which

has

guide

holes

on

both edges

while

the

paper

used

with

the

Friction

Feed

system does not

have

these

holes.

The

Friction Feed

system

may

be

used

with

the

tractor installed; however,

better

operation

can be acheived

if

it is

removed especially with single

sheets of

paper.

Note:

If you use

carbon paper or

other

duplicate form

paper

with

the

friction

feed

system,

take

extreme care when

setting up and printing out with

the

paper.

A

slight

shifting

of paper between

the

original

and the

copy could

occur

resulting

in

poor

printing or

improper

registration.

Warning!

The

Penetration

Control Lever must

always

be as

close

to

the

platen

as

possible;

otherwise

damage

to the Print Head may

result.

8.

Replace the

Top

Cover.

Note:

When the

Paper

reaches the

end of

a page, the

Ribbon

Installation/Replacement

If the Ribbon

Cassette

is

already

installed,

simply check to

see

that

it

is

properly threaded

between

the

paper and Print

Head.

See

Figure

9.

If the Ribbon

Cassette is not

installed,

or

if it must

be

replaced due to

excessive

wear,

faint

printing,

etc. ,

follow this

procedure:

1

.

Set the

Power

switch to OFF.

(Note:

When you turn

the

power

OFF,

any

information

stored

in the

Printer's

buffer

will

automatically

be

lost.)

2.

Remove the

of

the

printer.

4.

To

remove

the used Ribbon
