If the character cell is 5 x 7 with one dot of white space
10
or the total cell size is 5 x 8, the cell is also printed at
80 dots per inch. If three dots are to be added, there will be four dots total, and the cell will be 5 x 11. The
following table specifies lines per inch for various numbers of inserted dots.

Table 14 Rotated print spacing with 5 x 7 font
If a [LF] is used to specify the line spacing, it overrides the default table and sets spacing to 1 dot for 8 lines per
inch. If [ESC] J <n> is used, <n> specifies the spacing in n/216 (including the one dot white space). Note: n/216
will be rounded to the nearest n/80, and the finest resolution allowed will be 1/80 inch.
In rotated 90° or 270° mode, the print is done in all-points-addressable (APA) graphics. The intercharacter
spacing is adjusted with the normal line spacing commands. The [ESC] 3 <n> command is the most effective
command for adjusting intercharacter spacing. Line spacing much less than 12 cpi will force the characters to
overlap. (Spacing of 12 cpi is obtained with an [ESC] 3 <18>).
When 90° or 270° rotation is selected, only normal text can be printed. Underline, enhanced, emphasized, and
other attributes will not function. See the chart on page 34 for a list of available features.
In 180° rotation mode, all spacing commands are effective. The mode of operation simply inverts and mirrors
the print operation. All line spacing and print features are available. It should be noted that the feed direction is
not effected by any of the rotate commands.

Line graphics characters are 5 x 8 or 7 x 10 which allow touching characters as a default.
