When you turn the power on, your printer does not have any vertical tab stops. Sending
a VT command with no stops set results in a single line feed.
You can use the ESC B command to set a series of vertical tab stops. Once you have
set the stops, each time you issue a VT command the paper will move up to the next
stop position. You must enter the stops in ascending order, ending the series with a
NUL character. ESC B NUL will delete all vertical tab stops.
The actual position of the stops depends on the line spacing in effect when you send
the ESC B command. For example, at 6 lines per inch, a tab stop of 24 will appear four
inches from the top of the page, whereas at 8 lines per inch, the stop will be positioned
three inches from the top of the page. However, once you have set the vertical tab stops,
their position is absolute, and will not move, even if you change the line spacing later.
An ESC B NUL command will cancel all the vertical tabs which have been set.
Epson
Up to 16 stops are allowed.
