2.1.1.6 Notes on setting DIP switch 2-1 to ON

1) The printer mechanism stops but does not becom e busy when: an error has occ urred, the c over is open, printing stops due to a paper-end, or paper is fed using the paper feed button.

2) W hen setting DIP switch 2-1 to ON to enable handshaking with the printer, be sure to chec k the printer status using the GS a command and the ASB function. In this setting, the default value of n for GS a is 2. The printer autom atically transmits the printer s tatus, depending on online/offline changes.

3) When using DLE EOT, DLE ENQ, and DLE DC4 be sure that the receive buff er does not becom e full.

• When using a host that cannot transmit data when the printer is busy: If an error has occurred, DLE EOT, DLE ENQ , and DLE DC4 cannot be us ed when the printer

is busy due to a receive buffer-full state.

• When using a host that can transmit data when the printer is busy: W hen the receive buffer becomes full while transmitting bit-im age data, DLE EOT, DLE ENQ

or DLE DC4 used while sending the bit-image data is processed as bit-im age data. The data transmitted when the receive buffer is full may be lost.

Example: Check the printer status using GS r after transmitting each line of data and use

the 4 KB receive buffer. Transmit one line of data so that the receive buffer does not become full.

2.1.1.7 Notes on Resetting the Printer Using the Interface

2.1.2.2 Reverse Mode (Data Transmission from Printer to Host)

The STATUS data transmission from the printer to the host is proceeded in the Nibble or Byte mode.

• Description This mode allows data transmission from the asynchronous printer under the control of the host. Data transmissions in the Nibble Mode are made via the existing control lines in units of f our bits

(Nibble). In the Byte Mode, data transmissions are proceeded by making the eight-bits data lines bidirectional. The both modes fail to be proc eeded concurrently with the Compatibility Mode, thereby causing half duplex transmission.

In the bidirectional parallel interface spec ifications, the printer status transmiss ion is available by using the both-way communication facility in the Nibble/Byte Modes in accordance with the IEEE 1284.

In this case, different from in the RS-232 s erial interface spec ifications, the real- time interruptions from the printer to the host are disabled and thus precautions must be taken to the followings.

1) Allowable capacity of the printer internal buffer is 99 bytes (except ASB status). The status

signals exceeding this capacity will be discarded. To prevent possible loss of status, the host shall be ready for data acception (Reverse Mode).

2) When ASB is used, the host is preferably in the wait state for data acception (Rever se Idle Mode).

When this state is not available, the host shall enter the Reverse Mode to always monitor the presence of data.

3) When ASB is used, preference shall be given to the ASB status f or transmission over the other

status signals. Any accumulated ASB status signals left for transmission from the last to the newest ASB status transmission shall be transmitted together at a time as one ASB status showing the presence of change, followed by the latest ASB status.

Example: In the normal (wait) state, the ASB status is configured as follows.

First Status Second Status Third Status Fourth Status

0001 1000 0000 0000 0000 0000 0000 0000

When a sequence of operations ar e proceeded, the near end is detected and the printer cover is opened, then the printer cover is closed, the following pieces of data are accumulated.

First Status Second Status Third Status Fourth Status

①

0001 1000 0000 0000 0000 0011 0000 0000 Near end detection

②

0011 1000 0000 0000 0000 0011 0000 0000 The printer cover is opended.

③

0001 1000 0000 0000 0000 0011 0000 0000 The printer cover is closed.

When the ASB status is received following this, a total of eight (8) bytes of ASB will be transmitted as follows.

2.1.3.2 Switching between online and offline

The printer does not have an online/offline switch. The printer goes offline:

1) Between when the power is turned on (including reset using the interface) and when the printer is ready to receive data.

2) During the self-test.

3) When the cover is open.

4) During paper feeding using the paper feed button.

5) When the printer stops printing due to paper-end (in cases when an empty paper supply is detected by either paper roll and detector or the paper roll near-end detector with a printing halt feature set enabled due to paper shortage by ESC c 4).

6) During macro executing standby status.

7) When a temporary abnormality occurs in the power supply voltage.

8) When an error has occurred.

9) When the receive buffer becomes full. (*1)

*1 • Definition of “receive buffer full”

• When the receive buffer capacity is specified to 4 KB (DIP SW1-2 is Off):

• If the DIP SW2- 5 is off, when the rem aining space in the rec eive buffer drops to 128 bytes,

the printer status becomes “buffer full” and it remains “buffer full” until the space in the receive buffer increases to 256 bytes.

• When the receive buffer capacity is specified to 45 bytes (DIP SW1-2 is On):

• Regardless of the DIP SW2-5 setting, when the rem aining space in the r eceive buff er dr ops

3.8 Paper Sensors

The printer has 2 paper sensors as follows:

1) Paper roll end sensor

The sensor which detects whether paper is present or not.

When the sensor detects a paper-end, the printer stops printing.

2) Paper roll near-end sensor

The sensor which detects a near-end of a paper roll.

When the paper roll diameter becom es sufficiently small, the detects a near- end of the paper roll and the PAPER OUT LED lights. If the sensor is enabled by ESC c 4, the printer stops printing.

NOTE: After installing new paper roll, close the printer cover; then the printer restarts printing.

3.9 Cover Open Button

When the cover open button (located to the right of the cover) is pr essed, the printer cover is opened. When the cover is closed, the cover open button is latched.

NOTES: 1. Be sure to use the cover open button to open the printer cover.

2. Do not open the cover during printing.

3. Do not open the cover during auto-cutting operation; otherwise the mechanism may be

damaged.

3.10 Cover Open Sensor

The cover open sensor monitors the printer cover. W hen the sensor detects a cover open during printing, the error LED blinks and the printer stops printing. The printer recovers when the cover is closed. W hen the sensor detects a cover open while the printer is in the standby status, the printer goes offline. The printer recovers when the cover is closed.

NOTE: Whether the cover is open or not does not affect the status reported by the paper roll end

sensor.

3.11 Print Buffer-full Printing

When subs equent data is received after the printer processes one line of data in the print buf fer, the printer automatically prints the processed line and feeds the paper by one line (in standard mode).

3.12 Page Mode

3.12.1 General Description

The printer operates in two print modes only when the paper roll is selected as the print s heet: s tandar d mode and page mode. In standard mode, the printer prints and feeds paper each time it receives print data or paper feed comm ands. In page mode, all the received print data and paper feed commands are processed in the specified m emory, and the printer executes no operations. All the data in the memory is then printed when an ESC FF or FF command is received.

For example, when the printer receives the data "ABCDEF" <LF> in standar d mode, it prints "ABCDEF" and feeds the paper by one line. In page mode, "ABCDEF" is written to the specif ied printing area in memory, and the position in memory for the next print data is shifted by one line.

The ESC L command puts the printer into page mode, and all commands received thereafter are processed in page mode. Executing an ESC FF command prints the received data c ollectively, and executing an FF command restores the printer to standard mode after the received data is printed collectively. Executing an ESC S command restores the printer to s tandard mode without printing the received data in page mode; the received data is cleared from memory instead.

3.12.2 Setting Values in Standard and Page Modes

1) The available commands and parameters are the same for both standard and page modes. However, these values can be set independently in each mode for the ESC SP, ESC 2, ESC 3, and FS S commands. For these commands, different settings can be stored for each mode.

2) Although the m ax im um num ber of printable dots f or a bit im age when the paper roll is s elected as the print sheet is 512 in standard mode, 831 bit-image dots can be printed in the y direction (paper feed direction) in page mode. (This is possible only when the ESC W comm and has specified 831 printable-area dots in the y direction and the printing direction value of n in the ESC T command is 1 or 3.)

3.12.3 Formatting of Print Data in the Printable Area

Formatting of print data in the printable area is performed as follows:

1) T he printable ar ea is set us ing ESC W. If all printing and feeding are com plete before the pr inter receives the ESC W comm and, the left side (as you face the printer ) is tak en as the origin (x0, y0) of the printable area. The printable rectangular area is defined by the length (dx dots ) extending from and including the origin (x0, y0) in the x direction (perpendicular to the paper feed dire ction), and by the length (dy dots) in the y direction (paper feed direction). (If the ESC W command is not used, the printable area remains the default value.)

2) When the printer receives print data after ESC W sets the printable area and ESC T sets the printing direction, the print data is formatted within the printable area so that point A in Figure

3.12.2 is at the beginning of the printable area as a default value. (W hen a character is printed, point A is the baseline.)

Print data containing downloaded bit images or bar codes is f ormatted so that the bottom point of

the left side of the image data (point B in Figure 3.12.3) is aligned with the baseline. However, any Human Readable Interpretation (HRI) characters are printed under the baseline.

At the points labeled Point B, if characters (such as double-height character s) higher than normal

size characters or downloaded bit image character s are received, any part of the character higher than the normal-size character is not printed.

3) If the print data (inc luding the space to the right of a charac ter) exceeds the pr intable area before the printer receives a command (e.g., LF or ESC J) that includes line feeding, a line feed is executed automatically within the printable area. The print position, therefore, moves to the beginning of the next line. The line f eed amount depends on the values set by comm ands ( such as ESC 2 and ESC 3).

4) The default value of the line spacing is set to 4.23 mm {1/6″} and corresponds to 30 dots in the vertical direction. If print data for the nex t line contains extended charac ters that are higher than double-height characters, bit images taking up two or more lines, or bar codes higher than norm al characters, the amount of line feeding may be insufficient, resulting in overlapping of the characters' higher-order dots with the previous line. To avoid this, increase the amount of line spacing. The line spacing in Figure 3.12.4 requires 27 dots or more.

Example

When printing a downloaded bit image of six bytes in the vertical direction, use the following formula:

{number of vertical dots (8 × 6) - number of dots for feeding at the beginning of the printable area (21)} × vertical motion unit conversions (360/180) = 54

Therefore, 27 dots (54 pitch) are required for feeding. Use the following commands:

ESC W x

L, xH, yL, yH, dxL, dxH, dyL, dyH

ESC T n ESC 3 54 ← Set line spacing to be added. LF GS / 1 ESC 2 ← Reset the line spacing to 4.23 mm {1/6"}.

NOTE: Vertical and horizontal motion units are 1/360 in the vertical direction and 1/180 in the

horizontal direction; therefore, the position you specify varies depending on the printing direction. Setting the vertical motion unit to 1/180 using the GS P command does not change the current print position.

• With a parallel interface model, this command can not be executed when the printer is busy.

This command is executed even when the printer is offline or there is an error status when DIP switch 2-1 is on with a parallel interface model.

• When Auto Status Back (ASB) is enabled using the GS a command, the status transmitted by

the DLE EOT command and the ASB status must be differentiated. (Refer to Appendix G, TRANSMISSION STATUS IDENTIFICATION)

• Even though the printer is not selected using ESC = (select peripheral device), this command

is effective.

[Notes] • The status is transmitted whenever the data sequence of <10>H<04>H<n>

(1 ≤ n ≤ 4) is received.

Example:

In ESC ∗ m n

L nH d1...dk, d1=<10>H, d2=<04>H, d3=<01>H

• This command should not be used within the data sequence of another command that

consists of 2 or more bytes.

Example:

If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host computer) goes to MARK before n is transmitted and then DLE EOT 3 interrupts before n is received, the code <10>H for DLE EOT 3 is processed as the code for ESC 3 <10>H.

n Request 1 Recover from an error and restart printing from the line where the error occurred

2 Recover from an error aft clearing the receive and print buffers

[Details] • When the printer is disabled with ESC = (Select peripheral device), this command is effective.

• This command is effective only when an autocutter error occurs.

• The printer starts processing data upon receiving this command.

• This command is executed even when the printer is offline, the receive buffer is full, or there

is an error status with a serial interface model.

• With a parallel interface model, this command can not be executed when the printer is busy.

This command is executed even when the printer is offline or there is an error status when DIP switch 2-1 is on with a parallel interface model.

• DLE ENQ 2 enables the printer to recover from an error after clearing the data in the receive

buffer and the print buffer. The printer retains the settings (by ESC !, ESC 3, etc.) that were in effect when the error occurred. The printer can be initialized completely by using this command and ESC @. This command is enabled only for errors that have the possibility of recovery, except for print head temperature error.

[Notes] • The status is also transmitted whenever the data sequence of <10>H<05>H<n> (1 ≤ n ≤ 2) is

received.

Example:

In ESC ∗∗∗∗ m n

L nH dk, d1 = <10>H, d2 = <05>H, d3 = <01>H

• This command should not be contained within another command that consists of two or more

bytes.

Example:

If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host computer) goes to MARK before n is transmitted, and DLE ENQ 2 interrupts before n is received, the code <10>H for DLE ENQ 2 is processed as the code for ESC 3 <10>H.
