Also, when characters are enlarged vertically, the top of the
characters may not be printed on the first line of the page and
the characters on the second line or lower lines may overlap the
characters above them. This is because the characters are
enlarged from their baseline.
Because of this, when vertically enlarged characters are
contained in a line the print area must be secured so that the
vertically extended characters can fit. This is done by adding an
additional <LF> at the beginning of the print data line.
2) Paper feed command
In paper mode, the paper feed command and carriage return are
executed in units of dots. A 1/72-inch (0.353-mm) paper feed is
considered 1 dot. Since a 1-dot pitch in the horizontal direction
is 0.30 mm and a 1-dot pitch in the vertical direction is 0.353
mm, the paper amount that is fed while printing using a 90 or
270 rotation is less when compared with a 0 or 150 rotation.
As a result, when printing using a 90 or 270 rotation, execute a
test print, check the horizontal and vertical dot alignment, then
adjust the alignment as necessary.
3) The following commands are not executed in page mode, but
are stored and executed when the printer returns to line mode.
