PCL
2-51
Parameters for each command are listed in the command tables beginning on
page 2-53. Use the Symbol Set Tables to determine the decimal or hexadecimal value
for each parameter.
To determine a decimal or hex value, first locate the value of the parameter you require
in the Symbol Set Table. The decimal value is the value shown in the bottom of the cell
or box with that parameter. To find a hex value, go straight up the grid from the desired
parameter and read the value in the top heading. This is the first character of the hex
value. Next, go straight across the grid to the left of the parameter and read the value
in the left column heading. This is the second character of the hex value. For example,
ESC
(
←
) is coded 1B in Hex and 27 in decimal. (Any one of the three values
←
, 1B, or
27 might be used in your application. Read your documentation to determine which to
use.) The example on the following page sets the pitch of the primary font to 16.66
characters per inch.
Example:
ESC
(s16.66H
•
Decimal:
27 40 115 49 54 46 54 54 72
•
Hex:
1B 28 73 31 36 2E 36 36 48
Use the plus symbol (+) or the minus symbol (-) to select a position relative to the
current cursor position. For example:
ESC
&a6C
Move to horizontal cursor position, column six
ESC
&a+6C
Move six columns to the right of the current position
ESC
&a-6C
Move six columns to the left of the current position
Linking Commands
You can combine PCL emulation commands by linking them
if
the first 3 bytes of the
commands are identical. The combined, short form sends the first 3 bytes only once
in the string. To combine commands:
•
Use the first 3 bytes (characters) of the command only once at the start of the
command string.
•
Make the last letter of each command in the string lowercase.
•
Capitalize the last letter of the string.
For example, notice that the first 3 bytes of these two commands are the same:
ESC
(s10H
Select 10 characters per inch
ESC
(s4099T
Select Courier typeface
