The pitch can also be defined via the CHARACTER PITCH menu
item or via the control panel. The spacing can also be defined via a
multifunction command.
Function Dec. Hex. ASCII
Start double width 27 87 49 1B 57 31 ESC W 1
Stop double width 27 87 48 1B 57 30 ESC W 0
Start double width 14 or 0E or SO
Stop double width 20 14 DC4
before end of the line
With these commands you can extend characters to double their
normal width. If the actual character width is, for example, 12 cpi,
the printer will print at 6 cpi after a command for double width
printing. The following table shows all possible combinations.
The command Double width printing for one line is especially suita-
ble for titles and headings, as the function is automatically deacti-
vated at the end of the line. If a double width printing command is
to be cancelled before the end of a line, you must send a DC4 or ESC
W 0 command.
If double width printing is permanently activated via the command
ESC W 1, this function can only be cancelled by entering ESC W 0; in
this case DC4 has no effect.
Pitch Double width printing
10 cpi 5 cpi
12 cpi 6 cpi
15 cpi 7.5 cpi
17.1 cpi 8.5 cpi
20 cpi 10 cpi
If proportional spacing is activated, the use of double width print-
ing gives double width proportional printing. As this does not have
a fixed pitch, it is not shown in the table.
