mand, you should run the following BASIC program which prints a
sample of each of the possible combinations. As 256 combinations
are available in total, it takes some time until all examples are prin-
ted out on about 12 pages.

When the printer is switched on, tabulators are set automatically
every eight columns starting at the ninth column. If a tabulator cha-
racter (HT) is transmitted, the print head moves to the next set tab
position before printing the following character.
The set tabulator position relates to the set left margin (relative refe-
rence). The actual position of a tab depends on the actual pitch at
the time when loading the horizontal tab. When changing the pitch
the tabulator position does not move (absolute position).
It is mandatory to enter the tab positions in ascending order. The
parameter n
1
indicates the column position of the first tab, n
2
to n
k
accordingly the column positions of the other tabs to be set. Up to
32 (n
1
... n

) tabs can be defined. The position of a horizontal tab is
relative to the set left margin. The command sequence must be
ended with a NUL character.
