Selects elongated (double high) character printing for one line only. Elongated char-
acters are approximately double height but standard width.
The elongated character control code is a line–by–line print attribute; when the con-
trol code is received, one entire line of elongated characters is printed and then auto-
matically reset.
In P–Series protocol, elongated characters are formed by printing twice the number
of dot rows except for the top and bottom rows. In Serial Matrix protocol, elongated
characters are formed by printing twice the number of dot rows, including the top
and bottom rows.
When configured for double high print, P–Series control code BS (Hex 08) also se-
lects elongated character printing for a single line.
When using this feature with relative line slewing, the paper moves n + 1 lines rather
than n lines. Refer to the Vertical Format Units chapter for more information on
relative line slewing. When using small line spacing and the lines overlap, an unex-
pected print format may result.
The following sample program illustrates elongated character printing.
