sponding ESC sequences:

– Underlining
– Superscript/ subscript
– Double Superscript
Double impact print / bold print
With double impact print (= vertical boldpr int) theprint head goes over each line
twice. The paper is transported 1/180 inch after the first print and the same cha-
racters are printed again vertically and slightly displaced.
Withbold print (also called horizontal bold print) each dot of a character is printed
twice, whereby the second dotis displaced slightly to the right of the first dot prin-
ted.
Indouble impact print, the space between the dots is filled up, in (horizontal) bold
print, thelines of a character are intensified. Bold and double impact print can be
combined so that particularly bold characters result.
