account that each character occupies two columns. Character scoring (underline,
overscore and strikethrough) is not printed between the current print position and the
next tab when this command is sent.

This code is a terminator code and when received causes the contents of the print
buffer to be printed before advancing paper to the next vertical tab stop set by the
ESC B command.
This code will be executed normally, if vertical tab stops follow the current print
position. It will be executed like a FF code (EPSON mode) or like a LF code (IBM
mode), if the vertical tab stops follow the bottom of form position (which corresponds to
the form length if the bottom of form has not been set) or if the current position is
beyond the last vertical tab stop. It will be executed like an LF code if no vertical tab
stops have been set by the ESC B command. In EPSON mode, the vertical tabulations
are referred to the VHF channel selected by the ESC / m. If no VFU channels have
been selected, the printer assumes as default channel 0.
This command resets the double width printing set by SO or ESC SO command.
