1. Outline
1.1 Mode of Operation
The products of CD-S500 dot-impact-printer series are equipped with ESC/POS mode, CBM mode
and Star mode.
1.2 Character Set
All the printing data sent to a printer from a host computer is automatically changed into 1 byte
alphanumeric katakana character (ANK) corresponding to the character and sign.
Regarding the change in the character set and the mode that are set as factory default, please refer
to the instructions manual attached to each printer.
Cautions: Please refer to the appendix of this manual about the contents of the character set.

1.3 Control Commands
1.3.1 Explanation for Control Commands
Control commands control operation of printers, such as start/end of printing, and line feed,
paper feeding.
All functions associated with printing, such as type of character, enlargement of character, or format
are controlled.
Control commands vary with modes of operation. (See 1.1)
1.3.2 How to Send Control Commands
While there are several methods of sending control commands to a printer from a host computer,
method by BASIC is common.
Example .1
Character set “CITIZEN” is printed in normal size and enlarged size.
It is assumed that the printer is set under CBM mode.
Program Creation
Control commands in CBM mode lists that the command name for a double width large character is
SO, and 0E for hexadecimal code . Command name for canceling double width large character is SI
and 0F for hexadecimal code . Using these two codes, the resulting program will be as follows:
Program listing
10 A$="CITIZEN"
20 LPRINT CHR$(&HE)
30 LPRINT A$
40 LPRINT CHR$(&HA)
CITIZEN
CITIZEN
Printing result
50 LPRINT A$
60 END
Command for specifying/canceling of double width large character are sent under line numbers
20 and 40. As a result, while the same character set is printed in line numbers 30 and 50, they
are printed in double width expansion in line number 30, and printing is canceled in line
number 50.
In this manual, BASIC is used for sample program. Please refer to the manual of BASIC for further
details in creating a program by BASIC.

Setting the horizontal tab format/ESC D

[Decimal] 27 68 n1… nK NULL
[Hexadecimal] 1B 44 n1… nK NULL
[Parameter] 1<
n<255 0<k<32
[Description] ● The tab position is set to the position defined by “character width × n from the
left margin”. “k” indicates the number of horizontal tab position data to be set.
● At this time, the character width includes space between characters. If a
horizontal magnification of character is specified, the character width will
increase with the magnification.
● <nK> which denotes a setting position is processed in the increasing order and
ends at <00>h. When <nK> is equal to or smaller than its preceding <nK−1>,
the tab setting is finished. Then, the next data onward will be processed as
normal data.
● Settable tab positions are maximum 32. Tab positions specified exceeding this
limit is ignored.
● ESC “D” NULL clears all the set tab positions. The horizontal tab (HT)
command after clearing is ignored.
● Default is 7 × 9 and positions at eight-character intervals (9th, 17th, 25th,
33rd,... “n”th columns).

Horizontal length = d xL + dxH × 256 / Vertical Length = dyL + dyH × 256
● In STANDARD MODE, this command executes only the internal flagging of
printer without affecting printing in STANDARD MODE.
● If the horizontal start point or the vertical start point is out of the printable
area, this command will be canceled and the next data will be processed as
normal printing data.
● If the horizontal length or the vertical length is 0, this command will be
canceled and the next data will be processed as normal printing data.
● The character mapping position will be the start point specified by ESC T in
the print area.
If the (horizontal start point + horizontal length) exceeds the horizontal
printable area, the (horizontal printable area − horizontal start point) will be
taken as a horizontal length.
If the (vertical start point + vertical length) exceeds the vertical printable area, the
(vertical printable area − vertical start point) will be taken as a vertical length.
● If the calculation leaves a fraction, the fraction will be corrected with the
minimum pitch of the mechanism (203DPI) and the remainder will be omitted.
The horizontal start point and the horizontal length are calculated with the
basic calculation pitch 1/160. The vertical start point and the vertical length
are calculated with the basic calculation pitch 1/72.
