graphics

Your

printer

prints

images in successive columns

of

eight dots. The

LPRINT

statement

that

tells the

printer

to

do

this

has

three

com

ponents:

1.

The control

code

sequence that

puts

the

printer

into graphics

mode,

2.

The

number

of

co

lumn

s

of

graphics

to

be printed,

and

3.

The

coded

information that tells the

printer

which

dots

to

print

in each co

lumn

.

There are four

modes

of

GRAPHICS available

in

IBM Modes. They

differ in horizontal resolution,

or

density, which indicates

how

close toge

ther

the

dots

are

and

is

measured

by

the

number

of

dots

per

inch. All

modes

have

a vertical resolution of

72

DPI. For

reference, the

diameter

of

a

dot

is 0.4

mm

(1/72

inch). The

modes

are

discussed in

more

detail

in

the

next section

on

control codes.

The

maximum

width

of a graphics

image

is 345.4mm (13.6 inches)

for

th
