Chapter 3 Configuring The KSSM Emulation With Control Codes

Set Vertical Tabs In VFU Channels

ASCII Code ESC b m n1 nk NUL

Hex Code 1B 62 m n1 nk 00

Dec Code 27 98 m n1 nk 0

Purpose Sets vertical tab positions at the lines specified by n1 to nk (in the current line spacing) in tab set m, as measured from the top-of-form position.

The value for m specifies the number of the tab sets being changed; these sets of tabs are called vertical formatting unit (VFU) channels.

The values for n must be in ascending order; a value of n less than the previous n ends tab setting (just like the NUL code).

Where:

0 <= m <= 7

1 <= n <= 255

nk > nk-1

1 <= k <= 16

Comment Up to eight sets of tabs can be set.

Send the ESC / command to select a VFU channel other than channel 0; the VT (tab vertically) command then uses the settings for the selected channel.

Changing the line spacing does not affect previous settings for vertical tabs.

Sending the ESC b command clears any previous tab settings in that tab set.

Send an ESC b m NUL command to cancel all tab settings in the tab set m.

A maximum of 16 vertical tabs can be set in each VFU channel.

The printer stores all tab settings, even if outside the printing area; if you increase the page length to include previously set tabs, you can move to those positions with the VT (tab vertically) command.
