Horizontal tabulation
This control character may be located anywhere within a line and causes tabulation to the
next horizontal tab stop. Repeated specification of this control character causes horizontal
tab stops to be skipped. If you transfer HT HT HT HT, for example, the printer positions the
print head to the fourth horizontal tab stop.
Conditions for horizontal tabulation:
● At least one horizontal tab stop must be set.
● The printer ignores the control character if no horizontal tab stops are set or if tabulation
exceeds the end of the line.
● If the print head is on a set horizontal tab stop, the next horizontal tab stop is accessed.
Set print direction (bidirectional or unidirectional)
Unidirectional printing should be used if high positioning precision is required (e.g. in the
graphics mode). The default is bidirectional printing.
