User-defined Characters Sending information to your printer Once the -character is planned on the grid, you simply add the pin values for each column together, just as you do for graphics. The last step in defMng ,a character is to send this information to the printer. The command to define characters is relatively complex: ESC & 0 nl n2 al dz . . . dn You can define more than one character with a single command. The values nl and ti are the ASCII codes of the first and last characters you are defining. If you are defining only one character, n7 and n2 are the same. You can use any codes between 0 and 255 decimal for nl and n2 except the following codes: 7, 8, 9, 10, 11; 12, 13, 14, 15, 18, 19, 20, 24, and 27 decimal. Also, it is best not to define decimal 32, which is the code for a space. You can also use other codes by using the ESC 6 and ESC I commands. (See the Command Summary in Chapter 9.) For example, if you wanted to redefine the characters A through Z, n7 would be A (or ASCII code 65) and n2 would be Z (or ASCII code 90). So the command ESC ,h 0 AZ (followed by the appropriate data) would replace the characters A through Z. Following the specification of the range of characters to be defined in this command is one number (al) that specifies the width of the character and whether it uses the top eight pins or the bottom eight pins. The last part of the command (d1.. .dn) is the actual data that defines the dot patterns for each column of each character. Since a character can use up to eleven columns, you must supply eleven data numbers for each character even if some columns are blank. Note: Be sure to turn off DIP switch 2-l before defining characters. The ESC & command is invalid if this switch is on. 4-24 Software and Graphics

User-defined Characters

Sending information to your printer

Once

the -character

planned on the grid, you simply add

the

values for each column together, just as you do for

graphics. The

last

step in

defMng

character is

to send

this information to the

printer.

The command to define characters is relatively complex:

ESC

You can define more than one character with a single command.

The values

and

are

the ASCII codes of the first and last

characters you

are

defining.

If you

are

defining only one character,

and

are the same. You

can

use any codes between 0 and

255

decimal for

and

except the following codes:

10,

11;

12,

13,

14,

15,

18,

19,

20,

24,

and

decimal. Also, it is best not to

define decimal

32,

which is the code for a space.

You can also use other codes by using the

ESC

6 and

ESC

commands. (See the Command

Summary

in Chapter

9.)

For example, if you wanted to redefine the characters A through

would be A (or ASCII code

65)

and

would be

(or

ASCII

code

90).

So the command

ESC

AZ (followed by the appropriate

data) would replace

the

characters A through

Following the specification of the range of characters to be defined

in this command is one number

(al)

that specifies the width of the

character and whether

it uses the top eight pins or the bottom eight

pins.

The last part of the command

(d1..

.dn)

is the actual data that

defines the dot

patterns

for each column of each character. Since

character can use up to eleven columns, you must supply eleven

data numbers for each character even if some columns are blank.

Note: Be sure to

turn

off DIP switch

2-l

before defining

characters. The

ESC

command is invalid if this switch is on.
