printer. Never use the printer in a place of extreme humidity or any place where it can possibly be splashed by any liquids. If any liquids get into the printer, it could lead to fire, electric shock, or other serious accidents. Never touch the thermal head immediately after printing because it becomes very hot. Make sure that the thermal head is cool before setting papers or cleaning the thermal head. Be sure to hold the connector part of the power cable when disconnecting the cable. Pulling on the cable portion may cause it to fray and break. Power OFF the printer in any of the following cases: • The printer does not recover from an error. • Smoke, strange noise or smells erupt from the printer. • A piece of metal or any liquid touches the internal parts or slot of the printer. Using the printer in any manner other than for which it was designed may cause accidents or fire. 1.2 NOTES ON USE • Do not disassemble or repair the printer by yourself. • Do not drop the printer down on the floor or hit it against the walls. • Avoid exposure to the water. • Use the specified type of thermal paper. • When a trouble such as a paper jam occurs, turn off the power first to fix it. • The printer does not receive the data in some cases such as a paper out. Monitor the printer to check if an error occurs and not to stop the system. • Fix an error if something happens to the printer in order to prevent the whole system from hanging up. Thus, you need to take an action to prevent the error from affecting the whole system. • Immediately turn off the power if the printer fails (for example, you smell something strange, hear a noise, or smoke rises from the printer). After checking that such failure does not continue, contact your dealer or us.

The surface of thermal paper is specially processed using the chemical agent. And the color rises through the thermo chemical reaction process. Be aware of the following points. 1) Store the papers in a dry, cool and dark place. 2) Do not rub the papers with hard substance. 3) Keep the papers away from organic solvent. 4) Do not let the papers touched with vinyl chloride film, eraser or adhesive tapes for hours. 5) Do not put the papers on diazo print or wet copy that is just copied 6) Use the water-based glue (for example, starch glue and synthetic glue) when you glue thermal paper. 7) Adhesive tape may discolor the surface of thermal paper. Put two-sided tape on the back side of thermal paper if you need to tape it. 8) If you touch thermal paper with sweaty hand, your fingerprint may be left on the surface of thermal paper and the characters may printed unclearly. 9) If you use this printer to print receipts given to your customers, print the notice which states that the paper used is thermal paper and the instructions on how to keep it. 10) Use dedicated thermal papers only. 1.4 NOTES ON INSTALLATION Avoid such places with: 1) Dusty places 2) Unstable places and places that significantly shakes 3) Watery and oily places 4) Places which receive direct sunlight 5) Places where the temperature is 50°C or higher 6) Places where the temperature is 0°C or lower 7) Places where the electromagnetic interference or corrosive gas is generated 8) Places where the relative humidity is over 80% 9) Places where the significant temperature change may result in the formation of any condensation

This chapter describes the terms used in this manual. Dot A character or graphic image is composed of picture elements called dots. A dot corresponds to one of the thermal head heat elements. Dot line A line of dots arranged perpendicular to the paper feed direction. A dot line corresponds to a line of thermal head heat elements. One dot line consists of 384 dots in DPU-30. Character spacing The space separating contiguous characters on one character line. Line spacing The space separating character lines. Input buffer The memory for temporarily storing the data (characters and commands) received from the host device. Data is executed when fetched from the input buffer. The capacity of the input buffer is 4,096 bytes. Line buffer The memory for storing one line of character data fetched from the input buffer. When the line buffer is filled with character data (i.e. printing of an entire line) or the printing conditions are made valid through a command, the data in the input buffer is printed. The system configuration is shown in Figure 2-1. Printer DPU-30 Host device Input buffer Line buffer Figure 2-1 System Configuration

The printing executed when the data in the line buffer exceeds one line. Character data for one line is stored in the line buffer. When inflowing data exceeds the number of characters that can be stored in the line buffer, the data in the line buffer are printed. The overflowing data is stored at the beginning of the next line. Kanji size characters Kanji and user-defined characters. Standard size Extended graphics characters, katakana, and downloaded characters. characters Font The form of a character. A character is composed of a group of dots. The user can define a font using downloaded fonts, etc. Font size The size of a character. There are two font sizes, 16-dot font size and 24-dot font size. The sizes for standard size and Kanji size characters are shown below. Each size is represented as vertical dots by horizontal dots. 16-dot (height × width) 24-dot (height × width) Standard size characters 16 × 8 24 × 12 Kanji size characters 16 × 16 24 × 24 1-byte characters/ Classification by character codes. 2-byte characters Characters can be specified by 2 types of character codes: 1-byte character codes and 2-byte character codes. 2-byte character is effective when the situation of kanji mode is specified. Characters that can be specified by 1-byte character codes include: • Alphabets, Numbers, and Katakana • Extended graphics characters • Downloaded characters Characters that can be specified by 2-byte character codes include: • Kanji • User-defined characters

In the test print mode, characters (ANK, Kanji) and barcode are printed. Turning power ON with the !FEED_IN signal kept low starts the test print. 3.4.2 Hex Dump Print In the hex dump mode, the printer prints data input from the computer with hexadecimal numbers and characters. Set the dip switch No.7 ON, No.8 OFF, and turn the power on to enter the HEX dump mode. • If the input data exceeds a line long, such data will be printed as follows. If the input data does not exceeds a line log, set the !FEED_IN signal to Low. The rest of the data will be printed. • Turn off the power to finish the HEX dump mode.

Use the specified type of paper. 3.4.4 Adjustment of Print Density The print density is automatically adjusted by the head resistance, the number of dots, the head temperature, and the head voltage. The commands are also able to correct the print density. It can be adjusted in the range from 0% to 255% of the rated energy.

When the data with a lot of dots is printed, the print data may be missing and then, the printing may often continue in the state that each setting by the commands is reset. This is because too many print dots decrease the voltage, which results in the activation of the reset circuit of the printer. The commands which tend to increase the number of print dots are: • Underline • Reverse • Ruled line (in case that the number of dots is many) • Bitimage Case that a horizontal line is printed when printing a full line of “H” characters without spaces between the characters. The print density set command (case that the print density is set at over 100%) expands the length of strobe, which very often resets the settings, although this command does not increase the number of print dots. Be aware of these points when using the printer. 3.4.6 Memory 1. Input buffer memory An input buffer memory (RAM) with the capacity of 4,096 bytes is built in the printer. 2. User memory A user memory (RAM) with the capacity of 16,384 can be used when setting the printer in Mode 3. The data registered in this memory are cleared when turning off the power. This memory is used when using the downloaded characters, the user-defined characters, and the downloaded Bitimages. The memory used by the downloaded characters and user-defined character is restricted as follows. The remaining is used for the downloaded Bitimages. However, it can release the memory of the downloaded character and use-defined character so that ensuring the capacity for Downloaded Bitimage. The memory capacity immediately after the initialization Application Capacity (in byte) Downloaded character 4,560 User-defined character 1,080 Downloaded Bitimage 10,744 Total 16,384 The capacity for the downloaded characters and the user-defined characters is readily ensured at the initialization. This area can be released by a command to use the area for the downloaded Bitimages. When registering the downloaded Bitimages, calculate the remaining capacity of the memory before registering them. Be sure that the data with the larger capacity than the remaining capacity is ignored even if you trying to register such data.

All commands start with one of the following control codes (called function codes hereinafter): LF (0A16), CR (0D16), SO (0E16), SI (0F16), DC2 (1216), DC3 (1316), CAN (1816), ESC (1B16), FS (1C16), DEL (7F16) Some function codes form a command by itself and others are followed by parameters and/or image data. The number of bytes configuring a command differs from command to command. The shortest commands consist of 1-byte and the longest, some hundred bytes. 5.3 CHARACTER CODES This section describes the character codes in detail. The character codes are classified into two groups: 1-byte character codes and 2-byte character codes. The 1-byte character codes are used to print standard-size characters, whereas the 2-byte character codes print Kanji, user-defined characters. In Mode 1 and Mode 2, the printer uses only the 1-byte character codes. The following subsections describe the 1-byte and 2-byte character codes individually. 5.3.1 1-Byte Character Codes Used for standard size character printing. The hexadecimal codes valid as the 1-byte character codes are as shown below: • 2016 to FF16 (Some character tables make codes 7F16 and FF16 invalid.) 5.3.2 2-Byte Character Codes The 2-byte character codes are invalid in mode 1 and 2.

All the other codes are ignored. If the second-byte code is received along with a Kanji mode clear command, the next received data is processed as a 1-byte character code. 2116 through 7E16: First byte of a JIS Kanji code. 7F16 through FF16: Ignored.

0016 through 1F16: The first byte already entered is ignored. Function codes are processed as function codes. All the other codes are ignored along with the first byte. If the following code accompanies a Kanji mode clear command, the next received data is processed as a 1-byte character code. 2016: Ignored along with the first byte. 2116 through 7E16: Print Kanji or user-defined characters if the first byte is one of 2116 through 7E16. 7F16: Ignored along with the first byte. 8016 through FE16: Ignored along with the first byte unless the first byte is 0016. FF16: Ignored along with the first byte. For the correspondence between the 2-byte codes and the printed characters, refer to “Kanji Code Table” (as per JIS C 6226-1983). 5.4 FUNCTION CODE DESCRIPTION This chapter describes the commands in each function by the mode. 5.4.1 Function Code Description Format Each function code is described in the format below.
