4.5 Self-Printing Function

(1) Test printing

With power supplied as LF switch being press down, all characters available for use are printed out.
SEL lamp is held off during this stage, where BUSY signal is output.
On completion of test printing, normal operation is recovered.

(2) Dip switch information printing

With power supplied as LF/SEL switch is pressed, the dip switch/communication method (including set details for
serial) are printed.
At this point, SEL lamp is held off where BUSY signals are output.
Only with a 40-column type printer, following printing of dip switch information, printing is available in on-line
in hexadecimal dump mode.

(3) He x a de c i mal du mp mo d e

All data sent from the host computer are printed in hexadecimal codes.
When data for the last line are not sufficient for full one line, data of the last line are printed out with SEL switch
being pressed and deselected (OFF LINE).
This mode lasts till power is cut off.

4.6 Paper End. Mechanical Alarm

(1) Paper end

Print in g pape r s hort age i s d etec ted a nd i nfor me d wit h SEL la mp bl inki ng a t 0. 5 s eco nd i nter val s, whe re pri ntin g is
suspended. At this time, power supply to the motor and printing solenoid is stopped with BUSY signals output in the
host computer.
To recover from Paper End state, set new paper and press SEL switch twice. LF functions normally.
By pressing SEL switch twice, you can print, without changing paper, data for one-line input buffer on the remaining
page.

(2) Mechanical alarm

On occurrence of locked motor, any kind of trouble in the mechanism is suspected. Power supply to the motor and
printing solenoid is stopped and BUSY signals are output in the host computer. SEL lamp is then blinked at 1/4
second intervals. To recover from alarm state, eliminate the trouble cause and press SEL switch twice.
If it is in the course of printing, printing is started at the beginning of the interrupted line. (Content of the input buffer
is still held.) However, this dose not apply to a case where power has been cut due to a severe trouble.

4.7 General Remarks

(1) Do not print without ink ribbon properly provided. It may cause damage on the print head.
(2) Change ink ribbon before it becomes worn-out. Do not supplement ink.
(3) Be ca reful not to dr op, insi de the mai n body, a cl ip, a sett ing pi n, or any foreig n mat ter. It wil l lead t o machi ne

failure.

(4) To operate the printer, hold it on a flat stable table. If it not being flat or stable, the main b ody will be displaced by

vibrations while in printing, creating possible danger. Fixing it steadily is also important to avoid erroneous
operation.

(5) To clean the surface of the printer main body, never use organic solvent (alcohol / thinner / benzine, etc.)
(6) Paper, if left for long hours with a ribbon cassette mounted. Also, continuous printing, if conducted at a low

temperature, may cause thin printing due to ink features.

(7) Ribbon cassette, upon shipment, should not be mounted on a printer

(2) SI / SO and US / RS Commands

SI / SO codes function in the same manner as US / RS as long as 8-bit data are assigned (serial communication data
bit length), which, however, are divided, under 7-bit assignment, into SI (20H~7FH characters) print assignment and
SO (A0H~FFH characters) print assignment functions.

1. Standard letter assignment (SI / US) command:

With SI (0FH)/ US (1FH) codes input, lateral enlargement is cancelled and the data following are printed in sta ndar d
letters.
This command can cancel only lateral enlargement, which dose not apply to x 4 enlargement.

2. Laterally enlarged letter assignment (SO / RS) command:

With SO ( 0EH )/RS ( 1EH) codes i nput i n any colu mns, the data foll owi ng ar e pr inte d in print s en large d doub le i n
width. With line feeding or SI / SR code input, this command is cancelled.
Although standard and enlarged letters can be mixed within one line, automatic (buffer-full) printing takes place
when the number of columns reaches 24 (or 40) counted in standard letters.

(3) Data Cancel (CAN) Command

With CAN (18H) code input, print data held within the line before input of the CAN code are all cancelled.

[Receiving Data]

SO 123456 CAN ABC CR

[Results of Printing]
A B C * As data “1 2 3 4 5 6” are cancelled without the command “SO” cancelled, “ABC” is printed in

lateral enlargement.

(4) Inverted Letter Assignment (DC2) Command

When data are input with DC2 (12H) attached at the beginning of a line (invalid when attached to any other place),
data following are all printed in inverted letters.
To cancel this, input either DC2 again or DC1 (initial setting.)

(5) Initial Setting (DC1) Command

With DC1 (11H) input, various conditions set after power supply are cancelled and the state as a t supply of power is
restored. Content of the input buffer, however, is held unchanged.

(6) Continuous Paper Feed Assignment (ESC + “B” + n) Command

With ESC (1BH) + “B” (42H) + n code input, continuous paper feed at n-dot line is executed.
The n, however, should be a even dot line of 4≤ n ≤255.
An odd number, if assigned to n, is regarded as an even number of “n-1”.
If any scope other than the assignable scope has been assigned, this command is cancelled.
With this command input and printing data existing in a input buffer, printing is performed.
The printing line (10-dot line), however, is included in line feed volume “n”. With 4≤ n ≤9, inline space is made “0”.

(9) Registered Sentence Printing (ESC + “!” + n) Command

With ESC (1BH) + “!” (21H) + n code input, sentence already registered in the numeral assigned to n are printed.
Assign, to n, a numeral of 1 to 8. With any other numeral having been set, no execution takes place.

NOTE 1)

As much as 24 (40) bytes of data can be registered. In case that 24 (40) columns are exceeded on printing (because of
enlarged or x 4 letters having been assigned, etc.), printing is conducted up to 24(40)th column and the columns
overflowed are printed in the next line. Be sure to make registration in consideration of printing results.

NOTE 2)

With x 4 enlargement or inverted letters executed at printing, printing continues in that setting unless they are
cancelled.

(10) Character registration (ESC + “&”) command

1. For 24-column model (ESC + “&” + A1 + A2)

Individual patterns can be registered by entering the code ESC + & + A1 + A2, then entering the pattern data.
A maximum of 8 characters can be registered, and any address in the range of 20H to FFH ca n be used for t he
regis tratio n. Howeve r, if a n ew patte rn is re gistere d in an a ddress a lready i n use, ex isting data is c leared a nd the
newly entered data becomes valid. If more than 8 characters are registered, all existing character registration is
cleared.

[Address setting]
Specified address is matched to the character code and can be accessed likewise to the stored fixed character record.
If a fixed character is defined in the specified address, the fixed character becomes invalid. A1 signifies the starting
address for the registrations A2 is the ending address.

[Method of data transmission]
d-1 Single character registration
Sele ct t he ad dre ss to be def ie d (c ha ra ct er code) fr om a mon g 20 H t o F FH a n d des i gna te is as A1. W hen r e gis t er ing a
single character, starting and ending addresses match each other. That is, A1=A2.
<Example>
A6 × 6 dot matrix full dot pattern is to be registered in address 41H (code for the fixed character “A”). (Numerals are
hexadecimal.)

ESC + “&” + A1 + A2 + “Pattern data (6 byte)”
1B 26 41 41 FF•FF•FF•FF•FF•FF

In the successive controls, a 6 × 8 dot matrix full dot is output whenever the character code 41H is specified.
(Character “A” cannot be acces sed.)

d-2 Multiple character registration
By repeating the single character registration, a maximum of 8 characters can be registered. When defining multiple
characters in a successive address (character code), register pattern data for a maximum of 8 characters by
designation A1 as the starting address and A2 as the ending address.

Note)

A1<A2, A2 – A1≤ 7

[Pattern Data Configuration](For 24-Column Model)
Pattern data to be registered must consist of 6 bytes per character.
That is, pattern data configured by a 6 × 8 dot matrix is broken up into 6 vertically positioned units each of which is
represented by 1 byte of data. All together, 6 bytes of data are transmitted.
<Example> When transmitting the following data.

[Printing of Registered Letters]
To print registered character, in the same manner as printing other fixed characters, use the commands
(CR, LF, ESC + “B” + n).

2. For 40-Column Model (ESC + “&” + C1 + A1 + A2)

With ESC (1BH) + “&” (26H) + C1 + A1 + A2 code and the pattern data following input, a pattern is registered.
Total 224 characters are available for registration into addresses of 20H ~ FFH.
When two pattern data have registered in the same address, those initially registered are cleared and the new data
alone are made valid.

[Recognition of Use of Uppermost Bit]
For recognition of use or non-use of the uppermost bit by a character to be registered, set data to Parameter C1.

C1=0 (00H) : Uppermost bit not used.
Other than C1=0 : Uppermost bit used.

With 0 set to this parameter while the uppermost bit is in use, ×4 enlargement results in incomplete images for which
the uppermost part is lacking.

[Setting of Addresses]
A1 : Registration starting address (20H~FFH)
A2 : Registration ending address (20H~FFH)

[Pattern Data Configuration](For 40-Column Model)
Pattern data to be registered must consist of 9 bytes per character. That is, pattern data configured by 9×8 dot matrix
is broken up into 9 vertically each of which is represented by 1 byte of data.
All together, 9 bytes of data are transmitted.
<Example>
When transmitting the following pattern data :

Pattern data (9 bytes)

As the model utilizes the half-dot printing method. It is not capable of positing successive dots in the printing
(lateral) direction. Therefore, pattern, even if assigned in the position “*” to the right of “•” in the diagram above,
will not be registered as pattern data.

CBM-910 User’s Manual

CITIZEN

35

NOTE)

With 0 being set in “C1” parameter even if data have been registered in the uppermost position,
letter image registered is made incomplete.

(11) Registered Letter Valid / Invalid (ESC + “%” + n) Command

Whether a registered pattern is valid or invalid is set with ESC (1BH) + “%” (26H) + n code being input.
n = 1 (01H) : Registered pattern to be made valid. (Addresses for which no registration change has been conducted

are taken as inside fixed characters.)

n = 0 (00H) : Registered pattern to be made invalid. (Taken as in side fixed character sets.)

The initial setting is 0 (inside fixed character).
Even with letters already registered by pattern registration, printing of registered letters cannot be effectuated
unless the patterns registered are mode valid with this command.

NOTE)

This command is applicable only to the 40-column printer.

(12) Bit Image Printing (ESC + “K” + n1 + n2 + n3) Command

With ESC (1BH) + K (4BH) + n1 + n2 + n3 code being input, conversation from Text mode into Bit Image mode
takes place. The n1/n2/n3 assigns amount of transmission of bit image data which follows these.
Where, n1 represents the no. of bytes in lateral direction and n2 (lowermost)/n31 (uppermost) represent
the no. of dot lines vertical direction.

(Relations Between Data and Print-Out)

(Parameter Assignable Range)

Model n1 n2 n3
24 columns 1~18 0~255 0~1
40 columns 1~23 0~255 0~1

In case that assignment has been made out of the assignable range or n2 = n3 = 0 has been assigned, Bit Image mode
is cancelled and Text mode starts.
With this printer, on completion of read-in of 4-dot-line data or on completion of n1/ n2/n3 assigning data, lacking
data are printed as spaces.

NOTE 1)

With n1 = 23 having been assigned in 40-column Model, 4 dots from the lowermost column (LSB) are made invalid.
This is because the printing position in one line equals 180 dots.

NOTE 2)

On termination of bit image printing, Text mode is reinstated.

(13) ×4 Enlarged Letter Assignment (FS + “W” + 1) Command

With FS (1CH) + “W” (57H) + 1 (01H) code input, ×4 enlarged letters are assigned.
Data following this code are printed vertically and laterally twice enlarged.

(14) ×4 Enlargement Cancel (FS + “W” + 0)

With FS (1CH) + “W” (57H) + 0(00H) code being input, ×4 enlargement assignment is cancelled.

NOTE 1)

Although standard and laterally enlarged letters can coexist in one line, automatic (buffer-full) printing takes place
on reaching to 24th (40th) column counted in standard characters.

NOTE 2)

With both ×4 enlargement and double-width having been assigned, ×4 enlargement has priority.
