Code Sets D-25
Table D-5. Epson and IBM Control Codes
Function ASCII Hexadecimal Decimal Description
Ignore ........................................ NUL 00 or 80 0 or 128 The printer ignores this code unless it is used within an
escape sequence.
Continue printing?.................... ENQ 05 or 85 5 or 133 With the ENQ/ACK serial handshake in use, this code
causes the printer to return an ACK control code when it
can receive more data.
Bell ............................................. BEL 07 or 87 7 or 135 This code sounds the audible alarm for a brief period.
Backspace .................................. BS 08 or 88 8 or 136 This code moves the current print position one character
space to the left. If the current print position is the left-
most, the printer ignores this code.
Horizontal tab ........................... HT 09 or 89 9 or 137 This code moves the current print position right to the next
horizontal tab stop on the current line. If no tab stop is set
to the right of the current print position or the next tab stop
on the line is beyond the right margin, the printer ignores
the code. If the factory defaults are in effect, tab stops are
set every eight print positions across the page.
Line feed .................................... LF 0A or 8A 10 or 138 This code advances the paper one line space. If the current
line position is the last printable line on the page, the printer
performs a form feed instead of a line feed. If the automatic
carriage return mode is on, the printer performs a carriage
return in addition to the line feed.
Vertical tab............................... VT 0B or 8B 11 or 139 This code advances the paper to the next vertical tab stop.
If no vertical tab stop is set below the current line position
on the page, the printer ejects the page and advances to the
first line on the next page. If no vertical tab stops are set,
the printer performs a carriage return and line feed.
Form feed.................................. FF 0C or 8C 12 or 140 This code ejects a cut sheet or advances pin-feed paper to
the next top-of-form or top margin if one is set. This code
also moves the current print position to the left margin.
Carriage return ..................... CR 0D or 8D 13 or 141 This code moves the current print position to the left mar-
gin. If automatic line feeding is active, the printer performs
a line feed in addition to the carriage return.
Start double-wide print- .......... SO 0E or 8E 14 or 142 This code starts double-wide printing on the current line
ing for one line and doubles the character spacing to accommodate the
wider characters. A DC4 code or any control code or escape
sequence that causes paper movement ends double-wide
printing and resumes normal character spacing. The Start/
End Double-Wide Printing sequence also ends double-
wide printing.
