•Italic characters
•Super-/subscript
•Microfont
•Graphics
The
DMP 132 operates in three modes:
•
Data processing mode for quick output of program listings or data
• Word processing mode for letter writing or creating text documenta-

spaced characters produce letter-quality results. When you need aquick
printout, standard characters probably suit your needs,
In graphics
mode, you can use graphic data to draw nearly any type of graphic con-
figuration you desire.
With your ve·rsatile
DMP 132, you can determine not only character
style and printing mode, but you can also select the code set (control
code sequence) and character set.
Code sets:
•Tandy (original) code set
•Code set for IBM
80 CPS graphics printers
Character sets:
•Tandy character set
•IBM character set

Setting Up the DMP 132 1
This chapter shows you how to set up the DMP 132 so you can begin
using it
as soon as possible. Setting up the printer involves:
•Choosing alocation for the printer
•Installing the
paper rack
•Installing/adjusting the tractor feed unit
•Installing
or replacing aribbon
•Loading
paper
•Connecting the printer to apower source
•Connecting the printer to your
computer
•Powering up the printer
•Performing aself-test
Carefully unpack the
DMP 132, being sure to locate the ribbon and the
paper rack. Keep the empty box and packing material in case you ever
need to transport the
DMP 132.
Choosing aLocation
When you choose the location for your printer, be sure to consider the
following:
•
The work surface. Place the printer on asturdy surface.
•
The length of the printer cable. This determines the distance from
the
computer that you can place the printer.
•Space for paper.
Be sure to leave enough room for smooth flow of
tractor-feed paper.
•Noise generation.
Do not place the printer near noise generators
such as refrigerators
or industrial equipment.
Once you choose alocation for
the printer, you are ready to begin set-
ting it up.

Setting Up the DMP 132
Installing the Paper Rack
The paper rack keeps both fanfold and single- sheet paper feeding
smoothly into the printer. Mount this rack on the DMP
132 before op-
eration. To do so:
1. Open the printer cover.
2. Holding the paper rack upright, insert the tips of the rack onto the
supporters on both sides of the DMP 132,
as shown below.

3a. For single-sheet printing, pull up the folding leg and insert it into
the hole centered on top of the case.
3b. For printing on continuous fanfold paper, fold the leg and place
the paper rack in its horizontal position. Or, you can detach the
paper rack completely. However, note that proper paper flow
is
assured with the use of the paper rack.

Chapter 1
You can adjust the paper rack's paper guides for paper of various
widths. Pull
the left paper guide upward to remove it from the rack.
Then position it as you desire (within the range allowed). When using
narrow
paper, position the paper so that the left edge is within the
range
of the paper guide. This ensures proper operation of the paper
empty switch and also reduces the possibility of paper jam. Aftcr set-
ting asingle sheet, slide the right
paper guidc to the left to match thc
paper width.
Tractor Feed Unit
You can use the DMP 132 with either the tractor feed or friction feed
system.
The difference is that the tractor feed system is used with paper
(fanfold) that has guide holes on both edges, while the paper used with
the friction feed system does not have these holes.
When you use the friction feed system, be sure to remove the tractor.
When the
tractor is installed, the friction mechanism is released and the
DMP 132 might not feed the paper properly.
Installing the Tractor
1. Be sure the printer's power switch is off.
2.
Remove the paper rack and open the printer cover.
3.
Turn the paper loading knob forward to move the paper bail for-
ward.

Removing the Tractor
1. Turn off the printer.
2. Open the printer cover. Remove the paper rack if necessary.
3.
Turn the paper loading knob toward you to move the paper bail
toward the front.
4. Lift the tractor unit from the rear, then pull it upward.
5.
Turn the paper loading knob away from you.
6. Replace the paper rack and close the printer cover.

Ribbon Cassette
If the ribbon is already installed, simply check to see that it is properly
threaded between the paper and print head.
If the ribbon cassette is not installed, or if you need to replace it due to
excessive wear, faint printing, etc., follow this procedure:
1. Set the power switch to OFF.
Note: When you turn off the power, any information stored in the
printer's buffer
is automatically lost.
2. Remove the printer cover.
3.
To replace the ribbon cassette. grasp the fin on the old ribbon cas-
sette
and gently pull it upward.
4. Unwrap the new cassette. Before inserting the new cassette. tight-
en the ribbon

5. Gently slide the ribbon between the ribbon mask and the print
head. Press down on the left side of the cassette until you hear a
click. While rotating the ribbon feed knob in the direction of the
arrow, press down the right side of the cassette.
If the ribbon feed knob does not match up with the ribbon drive
mechanism, the cassette will not fall into place. Do not force the
cassette into place. Instead, fit it into place gradually while turning
the ribbon feed knob.
6. Once the new cassette is installed, tighten the ribbon by turning
the ribbon feed knob in the indicated direction.
7. Replace the printer cover.
Caution: Printing without paper or ribbon can damage the print
head or platen.

Connecting the DMP 132 to aPower Source
Before plugging the power cord into an AC power outlet, be sure that:
•The power switch
is set to OFF.
•The printer
is not yet connected to the computer.
Connect the
AC power plug to a120-volt, 60Hz, grounded AC outlet
or an approved power strip, such as the Radio Shack plug- in power
strip, Cat. No. 26-1396,
or the power switching system, Cat. No. 26-
