The print position is moved to the next horizontal tab stop. The tab posi-
tions, set by ESC "D", the Set Horizontal Tabs function, are not affected
by any changes in character pitch.
The factory default tab settings are at intervals of eight characters, in the
currently selected pitch. For the default tabs, the actual distance to each
tab position is affected by changes in character pitch.

tab (all tabs in ascending order), ... are subsequent tabs (maximum tabs:
32), nk is the last tab to set (any value less than the previous tab value
acts as a terminating character), NUL is the terminating character.
Clear Horizontal Tabs
All horizontal tab stops are cleared. It is merely a variant behavior of the
Set Horizontal Tabs function, where the NUL acts as an early terminating
character, as existing tabs normally clear before setting any new tabs.
