Carriage Return (CR)
0D
This control moves the current horizontal print position to the left margin. The
vertical print position does not change unless automatic line feed mode is active
(see “Set Auto Line Feed (ESC 5)” on page 197).
Shift Out (SO) / Double-Wide Print
0E
This control causes the printer to start double-width printing. Double-width printing
prints the characters twice as wide as the current character spacing. This results in
half as many characters per inch. Each character takes up the space of two
single-width characters. A Carriage Return, Line Feed, Form Feed, Vertical Tab,
Double-Wide Continuous Mode, or Cancel Double-Wide Print with vertical
movement specified cancels the Shift Out control code.
Shift In (SI) / Condensed Print
0F
This control prints graphic characters in condensed pitch (17.1 CPI or 20 CPI).
Shift In is a buffer terminating control; if printable data at a different
character-per-inch setting is buffered, that data is printed before the setting is
changed. The current print position becomes the next printable column at the new
character-per-inch setting. CPI can be changed within a print line, and this control
changes the maximum number of characters that can be printed on one line.
A combination of 10 CPI and Condensed Print sets the printer to 17.1 CPI
regardless of the 20 CPI setting in the Power On Configuration menu.
A combination of 12 CPI and Condensed Print sets the printer to 20 CPI when
20 CPI=YES is set in the Power On Configuration Menu. A combination of 12 CPI
and Condensed Print sets the printer to 12 CPI when 20 CPI=NO is set in the Power
On Configuration menu.
Device Control 1 (DC1) / Select or XON
11
This control has different meanings depending upon the currently active interface.
v Parallel interface (Select): DC1 selects the printer.
v Serial interface (XON): DC1 is treated as a NUL if received from the host. The
printer sends DC1 (XON) to the host to control data pacing if XON/XOFF pacing
is selected.
Device Control 2 (DC2) / Select 10 CPI
12
This control sets 10 characters per inch. DC2 is a buffer terminating control; if
printable data at a different characters-per-inch setting is buffered, that data is
