printing
The commands SI and ESC SI have identical functions. If the print
pitch is 10 cpi, then 17.1 cpi is used in condensed printing. With a
print pitch of 12 cpi condensed printing is at 20 cpi. If a DC2 com-
mand is sent, the printer returns to the print pitch which applied
before SI.
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 or
for one line 27 14 1B 0E ESC SO
Stop double width 20 14 DC 4
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 suitable for titles
and headings, as the function is automatically deactivated at the
end of the line. If a double width printing command is to be cancel-
led before the end of a line, you must send a DC4 or ESC W 0 com-
mand.
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.
