Use these commands to produce characters twice as wide as regular characters. For
example, if the current character pitch is 12 CPI, double width characters will print at
6 CPI. The Character Width table shows all the possible combinations. The one-line
double width commands are especially convenient for titles and headlines, since they
turn off double width printing automatically at the end of the line. If you want to cancel
one-line double width printing before the line ends, send a DC4 or ESC W 0 command.
(But note that when you use ESC W 1 to turn on continuous double width printing, the
only way to stop it is with ESC W 0; DC4 has no effect.)
You can also choose continuous double width printing in Menu Select mode.

The one-line double width command ESC SO is identical in function to the SO
