A&D 191 - Manual (Page 24)

Enlarged printing may be selected by sending both the
double height command (control code 14) and the double
width command (control code 15). The control codes may
be sent in either order, but because of the double width
restrictions, the codes should be sent at the beginning of
a line.
When the printer receives this control code it will immedi-
ately reset the sequence number to 00000.
A standard character line is made up of ten dot lines. Eight
of these dot lines are used for the printable character and
two are used for space between lines. When using
character graphics it is desirable to eliminate the two
blank lines so the graphic characters connect together.
Sending a CHR$(17) (control code 17) anywhere on a line
of data will stop the printer from putting space between
that line and the next. If a CHR$(17) is not on a print line,
the normal space between lines will be printed.
