Select Vertical Tab Channel
Escape sequence: ESC / c
Hexadecimal: 1B 2F c
This command selects one of the eight preset VTCs. The printer
subsequently uses this VTC for all vertical tab operations. The
variable c specifies the VTC number (0 through 7).
Set VTC Tab Stops
Escape sequence: ESC b c n1...n16 NUL
Hexadecimal: 1B 42 c n1...n16 00
This command sets up to 16 vertical tab stops (in the current line
spacing) for the VTC specified by the variable c. Subsequent line
spacing changes do not affect these settings. Each of the variables
(n1 through n16) can be any value in the range of 0 through 255.
The tab settings must be entered in ascending order (n1, n2, and so
on), that is, the value of each, succeeding, a variable must be greater
than the one preceding it. Any n variable with a value of 0 (00)
terminates the command. The command ESC b c 0 clears all tab
stops for the VTC specified by the variable c.
Clear All VTC Tab Stops
Escape sequence: ESC b c NUL
Hexadecimal: 1B 62 c 00
This command clears all vertical tab stops from the VTC, specified
by the variable c.
Clear All Vertical Tab Stops
Escape sequence: ESC B NUL
Hexadecimal: 1B 42 00
This command clears all previously set vertical tab stops from VTC 0.
