model

I

system,

replace

the

ribbon,

close the cover

and the

printer will

resume

printing

without

loss or

insertion

of

data.

With

a

model

II

system,

you

will have

to

type continue

(after replacing

the ribbon)

and

then the

printer

will

continue

printing

from

the

stopped

head

position.

However,

you should be

aware

that

the

entire

current

line

will

be restarted

from

this location, therefore

there

may

be

some

duplication

at

this

Front

Cover

Interlock

The

front

cover

incorporates a special

interlock

switch

-

-

if

the

cover is

opened,

the

printer

automatically

will

stop.

When

the

cover is closed

securely,

the

printer

will

continue

to

function

as

noted

above

under "Notes

Control

Codes

According

to

the

American Standard

code

for

Information

Interchange,

there

are

32

control

codes in addition to the codes for

the

printable

characters.

(Control

codes

are

sent

as

data,

but

the

receiving

device interprets

them

as

abbreviated

instructions,

communication-status

messages,

etc.)

The

recognizes

the

following

control

codes

and

ignores

any

others.

Special Note:

If

you

use

this

printer

with a

Model

I TRS-80 and

have

BASIC

programs

which

use

top-of-form

(I.E.

programs

for

creating

continuous

form

formats),

you

may

require

a

special

driver

program.

This

is

available

free

of

charge

through

your

local

Radio

Shack store

or

Computer

Center

(special

part

number

700-2007).

(Without

this

special

driver

program

your

BASIC

programs

-

-

set up

con-

tinuous

forms

-

-

may

position

improperly

at

the

top

of

each

new

page

of

a

form.)

17

External

Program Mode

On

some

special

wheels,

such as

OCR-B

10

and

others,

you

need

to

"externally"

control the

following

(the box of such

wheel

shows

"Require

Special

Programming").

•

Spacing

between printed

character

(Proportional

space

mode

only)

•

Amount

of

ribbon

feed

•

Hammer

impression

level

(For

ordinary

fonts,

these

are controlled

by

the

program

in

ROM.)

Each character or

symbol

requires

a

different

amount

of

the

three

factors

above.

First,

you

must

enter External Program Mode by

sending

control

codes 27,

24

(IB,

18).

Then

send

a two-byte code

for

each character/symbol.

The

first

byte

is

the

ASCII

code,

the

second

byte

contains the data specifying the

printing

format.

Refer

to

the

table

on

Page

19.

For

example, capital

letter

"T"

in

OCR-B font

requires

1/10"

spacing,

normal

ribbon

feed,

and

level

4

of hammer impression.

1/10"

(=

6/60")

is

0110.

Normal ribbon feed

is

1.

Level

4

of

hammer

impression

is

100.

Put

together,

we

get 01101100, which

is

108

is

in

decimal,

6C in

hexadecimal.

By

sending

this data (108 or

6C),

capital

"T"

is

printed

properly

on

OCR-B

10

font.

The code

for

each character/symbol

is

specified

in the

code

chart

provided

with

each

wheel.

To return

to

normal

mode, send code 27,

25 (IB, 19).

When you

turn

the

power

switch

off and

then switch back on again, the

Printer will

be in

the

normal

mode.

Special

Functions

Auto

NL

(New

Line)

In the

following

cases,

the

printer

will

automatically

execute

a

new

line

function

under

the

following

conditions

(carriage

return

with

line

feed)

:

1.

In the

10

pitch

mode,

when

the

carriage

moved

over

to

the

136th

position.

2.

In the

12

pitch mode,

when

the

carriage

moves

over

to

the

163rd

position.

3.

In

the

proportional

spacing

mode,

when

the

carriage

moves

to

within

8

units

(8/60")

from

the

right

margin (right

margin is

13.6"

from

the

left

margin).

Note:

Auto

NL

may

not execute

at

these

exact

positions

(noted

above)

if

the

pitch

has

been

changed

during

the

execution

of

the

current

line.

Optimizer

To optimize

printing time

(more

efficient

carriage

movement),

when

every

a

function

code

(SP,

BSP,

1

unit to

6

unit

SP, LF including

NL,

BLF,

1/2

LF and

1/2

BLF)

is

encountered

in

a

program

within

10

milliseconds

of

each

other,

the

printer

temporarily

stores

these

codes

until

the

following

data is

transferred:

1.

Character codes

are

inputted.

2.

Function

codes

are inputted

with

intervals

of

10

msec

or

moe.

Then, these

above stored

function

codes

are

executed

at

one

time.

For

example,

when

10

LF

codes

are inputted

with

less

than

10

msec

intervals,

the

printer

will

automatically

feed

10

lines

at

one

time upon

receipt of

the next code

(not

one

line

feed,

repeated

ten

times).
