3.4.1 Test Print

The detail of the setting by dip switches is confirmed by test printing.

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.

3.4.3 Paper Empty (Paper Out) Detection Function

Detects the existence of paper using the photo interrupter. 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.

3-7

3.4.5 Resetting the Printer While Printing

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.

5.2 FUNCTION CODES

All commands start with one of the following control codes (called function codes hereinafter):

LF (0A FS (1C

), CR (0D16), SO (0E16), SI (0F16), DC2 (1216), DC3 (1316), CAN (1816), ESC (1B16),

), 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:

• 20

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. The 2-byte character codes are used to print Kanji, and user-defined characters when in the Kanji mode.

• The first byte through 2016: Function codes are processed as function codes (See 5.2 FUNCTION

CONDES). 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.

through 7E16: First byte of a JIS Kanji code.

through FF16: Ignored.

5-5

• The second byte 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.

: Ignored along with the first byte.

through 7E16: Print Kanji or user-defined characters if the first byte is one of 2116

through 7E

: Ignored along with the first byte.

through FE16: Ignored along with the first byte unless the first byte is 0016.

: 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).
