Specifications

Notes
• The specification of orientation shall be made at the beginning of the line. If it is made in
the middle, it is ignored. This specification continues to be valid until it is canceled.
• It is not permitted to flip 6x7-dot mode fonts and OCR-B fonts.
• Only character fonts that have equal enlargements in both vertical and horizontal directions
can be flipped.
• The orientation once it is set up continues to be valid until it is canceled.
Buffer full printing
It is possible to switch the buffer full printing with an appropriate ESC command to
enable or disable. The operation after switching is as follows:
• If buffer full printing is enabled
If character codes are being printed and if the line buffer is full before the print start
conditions are met, a whole single character that may extend beyond the right
margin will be printed on the line following a line feed. For example, in the case of
16-dot Kanji characters, thirty-six characters can be printed on a line if the
character-to-character spacing is specified as being zero. In this case, if the
thirty-seventh character is a character code, this will be printed at the top of the
next line after the thirty-six characters have been printed and a line feed has
effected.
Figure 2.20
• If buffer full printing is disabled
Character codes received after the character that extends beyond the right margin and
before the print start conditions are met are ignored.

th
character
This character (“お”), which comes at the
end of a line, will be ignored, since it is not
fully contained within the line. In addition,
this line will be successfully printed when
the print start conditions are met (output of
CR/LF).
