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
Start double width
Stop double width
Start double width
for one line
Stop double width
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.
