CHAPTER 1

TERMS USED IN THIS MANUAL

This chapter describes the terms used in this manual.

INPUT BUFFER AND LINE BUFFER

When the DPU-S445 (hereinafter it is referred to as “printer”) receives data (character codes and commands) from the host devices, it stores the data in the printer input buffer. The input buffer has a capacity of 4K bytes (4096 bytes). Then, the printer retrieves data from the input buffer. If data is character code, data is stored into the line buffer. If data is command, data is executed as command immediately.

The printer inputs character codes to the line buffer until the amount of character codes reaches the amount to be printed on one line, then prints the characters. The printer repeats this operation to print all the character data.

The relationship between the input buffer and line buffer is illustrated in Figure 1-1.

Host Device

Input Buffer

Line Buffer Print Operation

One Line of Characters is Printed.

Figure 1-1 Relationship between Input Buffer and Line Buffer

1-byte characters and 2-byte characters

The printer can print two-size characters; 1-byte characters and 2-byte characters. Table 1-1 lists the character types which can be printed by 1-byte and 2-byte characters.

Table 1-1 Character Types and Relationship between 1-byte and 2-byte Characters

	Character Types
1-byte characters	Katakana character (ANK)
	Extended graphics character (IBM Compatible)
	Codepage 1252
2-byte characters	Kanji, user-defined character

*1 The size of a character to be printed differs depending on the font specified. (See 2.1 Printer Specifications.)

1-1

Line Spacing

Line spacing is the space between the lines of printed characters (See Figure 1-2).

ABC

Line Spacing

ABC

Figure 1-2 Line Spacing

This printer use a line thermal print mechanism, therefore, a paper feed step is necessary before printing characters or bit images.

The line feed command with printing feeds the paper for height of characters or bit images. Therefore, a paper feed amount which is smaller than character or bit image height is ignored. Printing with underline feeds the paper 4 dot lines in addition to the character height.

Line feeding without printing feeds the paper for specified line feed amount.

Character Spacing

Character spacing is the space between each character in the horizontal direction (See Figure 1-3).

A B

Character Spacing

Figure 1-3 Character Spacing

Line

The word “line” in this manual indicates a line of characters. For example, the sentence “the printer feeds paper one line” indicates that the printer feeds paper a line of characters.

Dot Line

The words “dot line” in this manual indicate a line of dots in the vertical direction. For example, the sentence “the printer feeds paper by one dot line” indicates that the printer feeds paper by the space of 1 dot.

Paper Auto-loading

The paper auto-loading function which can loads the cut paper from the paper slot automatically by using the paper feed motor.

Notation in the Technical Reference

Hexadecimal

Hexadecimal is showing as follows;

Example: 0AH (a hexadecimal unit 'H' is added behind a hexadecimal number.)

Character string

A character string is showing as follows;

Example: 'G' (a character string 'G' is enclosed with a single quotation mark.)

2.4PRECAUTIONS FOR USE

Always print the two-dimensional bar code and ladder bar code (its bar is to be printed verticality to the printer) within 0 to 40°C to ensure the bar code's reading accuracy.

The two-dimensional bar code and ladder bar code printing always requires the low speed mode to ensure its reading accuracy. Set the print speed to the low speed mode by using Motor Speed Select (GS 'E') command.

The height of the ladder bar code requires over 10 mm to ensure its reading accuracy.

To print data at a temperature of 15°C or lower, be sure to set data for black printing to 78 mm or less (see figure below).

At a low temperature, the total number of black printing areas (w1 + w2 in the figure above, for example) should not exceed 78mm for parts having high printed ratios* (including the ladder bar code part).

Be aware, in particular, that reverse printing and ruled line tend to increase the ratio.

*Parts where many black dots are used when viewed in the direction vertical to the paper feed direction.

Use of the battery pack at low temperature will run out of power in a shorter time.

When printing ruled lines, a 2-dot configuration is needed. In case of a 1-dot configuration, the printed lines may be invisible.

Always use the printer within the shadowed range depicted in figure below Relationship between Temperature and Humidity.

When using a Bluetooth interface, the radio environment around the printer may cause a failure in communications. This is due to the specifications of Bluetooth, which is a radio communications standard.

When handling this product, be aware of static electricity. If the static electricity is discharged, this could case communication failure. When this problem occurs, disconnect the USB connector that is connected to the host device and wait few seconds before connect it again.

When the printer is left unused for a long period of time, a white powder appears to the surface of platen. (This is the powder by which an ingredient of a thermal paper was recrystallized.)

If the powder appears to the platen, wipe the platen with ethanol and use the printer after ethanol has dried completely.

Also, make sure not to adhere ethanol except the platen area. If ethanol adheres except the platen area, wipe it off immediately.

(NOTE) Refer to "SAFETY PRECAUTIONS" and "OPERATING PRECAUTIONS" on DPUS445 SERIES USER'S GUIDE which be included with the printer for other precautions.

2-10

CHAPTER 3

INTERFACE

This chapter describes 4 types of the interface specifications which are required to connect the host device with the printer.

Irrespective of the interface used, amount of the input buffer in the printer is 4k bytes, and transmission buffer is 768 bytes. If the transmission buffer becomes the condition of the buffer full, the printer waits data processing until the buffer can be received data. Be aware that printing process does not performed in that meantime.

(5)Data reception

Busy control

In Busy Control, RTS outputs MARK until the printer is ready to receive data after power ON. After the printer is ready, RTS outputs SPACE and the received data is input to the input buffer. When there are 33 bytes or less remaining in the input buffer, RTS outputs MARK. The host device does not transmit data during RTS outputs MARK. When the input buffer is ready to receive data (there are 65 bytes or more in the input buffer) after stopping data reception, RTS once again outputs SPACE. If an error occurs in the printer, RTS outputs MARK and inhibits data entry until the error is cleared. If an error is cleared, RTS outputs SPACE again.

For RTS output when an error occurs, the setting is changed by Busy Output When Error Occurs at function setting.

Xon/Xoff control

In Xon/Xoff control, TXD outputs Xon code (11H) from power ON until the printer is ready to receive data. Received data is input to the input buffer. When there are 65 bytes or less remaining in the input buffer, TXD outputs Xoff code (13H). The host device does not transmit data while Xoff code is received. When the input buffer is ready to receive data (there are 129 bytes or more in the input buffer) after stopping data reception, TXD once again outputs Xon code. When this

control method is selected, the RTS signal always outputs SPACE. If an error occurs in the printer, TXD outputs Xoff code and inhibits data entry until the error is cleared. When the error is cleared, TXD outputs Xon code again.

For Xoff code transmission when an error occurs, the setting is changed by Busy Output When Error Occurs at function setting.

Data reception error in serial communication

When Parity is selected as Yes by the function setting, a '!' is printed next to data in which a parity error occurred and a '?' is printed next to data in which any other error (framing error, etc.) occurred. If a serial data reception error occurs, no error indication other than the printing of '!' and '?' is performed (for example, the ERROR lamp does not light).

(6)Data transmission

Busy control

In Busy Control, the conditions which transmit status information to the host device from the printer are as follows;

When CTS Control of function setting sets to Enable, the printer sends data from TXD after confirming CTS status as SPACE.

When CTS Control of function setting sets to Disable, the printer sends data from TXD regardless of the condition of the host device.

Xon/Xoff control

In Xon/Xoff control, the conditions which transmit status information to the host device from the printer is that the printer sends data from TXD regardless of the condition of the host device.

(NOTE) Be aware that if the transmission buffer becomes full, the printer does not print until the buffer is available.

(4)Data reception

USB data reception uses a bulk-out transfer method.

The data are received even during the printing operation, and when the data accumulate in the input buffer by the amount of input buffer + 2 packets, the NAK response continues until amount of the input buffer becomes 129 bytes or more.

The number of bytes that can be received with one packet is maximum 64 bytes. When an error occurs, the NAK response continues until the error is cleared after receiving data of 2 packets.

For the operation when an error occurs, the setting is changed by Busy Output When Error Occurs at function setting.

(5)Data transmission

USB data transmission uses a bulk-in transfer method.

The response data are stored temporarily in the transmission buffer, and a response is made to the bulk-in packet request from the host device. If no transmission data exist, the zero length data is returned when the bulk-in request is received. The number of bytes that can be transmitted with one packet is maximum 64 bytes.

(NOTE) Be aware that if the transmission buffer becomes full, the printer does not print until the buffer is available.

Flow control is performed by the TinyTP layer when connecting with 3-Wire or 9-Wire. Xon/off control and line status control are not supported.

(7)Command response processing during IrDA transmission

If the printer receives a command that requires transmission of data from the remote station during IrDA transmission, and then stores the data in the transmission buffer and transfers them at transmit timing to the remote station.

The printer clears a response data in the transmission buffer when transmission to the remote station is disconnected for busy state. When the remote station is in disconnection, the printer does not store the data in the transmission buffer and the data is cleared.

However the printer transfers the status regardless of the remote station state when initial automatic status transmission is enabled.

The printer transfers status when the remote station is connected again if automatic status transmission has not deactivated by power off.

(NOTE) Be aware that if the transmission buffer becomes full, the printer does not print until the buffer is available.

3.3.3 BHT-Ir Specifications

The printer also supports BHT-Ir communication specified by DENSO CORPORATION.

The printer can receive data from the 'BHT-6500' made by DENSO CORPORATION when Data Input Mode SWDIP2-1 and SWDIP2-2 is selected to BHT-Ir.

The inherent processing of the printer for BHT-Ir communication is shown below: See BHT-Ir protocol specification for details of the protocol.

(1)ID

Printer ID: 3445H (fixed)

(2)Text format

Only text is valid.

Files with 'PD3', 'FN3' or 'EX3' extension can not be processed.

(3)Input buffer full processing when receiving header.

Upon receiving the header, the printer inhibits connection with the host device when the remaining amount of the input buffer becomes 512 bytes or less after subtracting the field number of the data text indicated in heading text.

(4)Input buffer full processing when receiving data

Upon receiving data, the printer sends WACK supervisory sequence to a host device for requiring temporarily delay of the data output from the host device as the input buffer full state when the remaining amount of the input buffer is 255 bytes or less.

Then, the printer sends the ACK supervisory sequence to the host device to restart data transmission when the remaining amount of the input buffer is 512 bytes or more.

The printer transfers the EOT supervisory sequence and stops when the input buffer full status continues more than 1 minute.

(5)Command response processing during BHT-Ir transmission

No response command is transferred in BHT-Ir transmission mode. Although response data is generated, it is discarded.

(2)Security

The printer does not set with PIN code or the Link Key in default. Bluetooth device uses security mode 1, so no encryption is used.

Bluetooth device becomes security mode 3 if PIN code is set by Set default/Set test print header command or Bluetooth Link Key selection of the function setting is set to Enable, and encryption is used. When the setting of Bluetooth Link Key is Disable and selection of PIN code is canceled, Bluetooth device becomes security mode 1 again, and no encryption is used.

(3)Input buffer

Capacity of input buffer for internal Bluetooth module is 3Kbytes. Received data is stored in the input buffer of Bluetooth module, and then these data is to be processed after data transfer to input buffer of the printer.

If an error occurs, the printer stops receiving data after data that stored into input buffer of Bluetooth until the error is cleared.

For the operation when an error occurs, the setting is changed by Busy Output When Error Occurs at function setting.

(NOTE) Be aware that if the transmission buffer becomes full, the printer does not print until the buffer is available.

(4)Link key saving

If the Bluetooth Link Key selection of the function setting is set to Enable, the printer saves the link key to connect with the host device in the pairing process.

The host devices can be saved up to 10. When requiring to save the 11th host device, perform the pairing after clearing the saved host devices in the printer.

To clear the all of saved host device data, set the Bluetooth Link Key selection of the function setting as Disable after setting Data Input Mode of the function setting as Bluetooth. The printer clears the stored host device data after the above process.
