( 5 ) E S C 0
Input of the ESC 0 causes the subsequent line spacing to be set at 1/8 inch.
(6) ESC 2
Input of the ESC 2 causes the subsequent line spacing to be set at either 1/6
inch or 1/8 inch depending on the initial set condition of the DIP switch pin
1-1.

This code specifies the vertical tab stop positions.
The first 8 valid tab stops per page are recognized in the Printer; subsequent
tab stops are ignored.
A tab stop set at a line exceeding the form length specified by ESC C + n is
ignored. If the form length is set to 66 lines upon initial power application,
the last tab stop (n

)
D
should be less than 66.
Tab stop numbers must be received in incremental numerical order. (n

To execute tabulation, the VT code should be input. Once vertical tab stops
are established, the data will be valid until new tab stops are specified. If no
tab stop is set, the VT code behaves like the LF code. Therefore, the paper is
advanced one line after printing.
Receipt of “ESC B” code causes the Printer to accept the following codes as
tab stop line numbers until the NUL code is input. The lack of the NUL code
will cause incorrect data printout.
The form length must be set by “ESC C + n” or “ESC C + 0 + m” code prior
to setting tab stops. The VT setting is cancelled by input of “ESC C + n” code.
Therefore, the tab setting should then be established again. Input of “ESC B”
code followed by only the NUL code cancels predetermined tab stops.
