ZG310 Thermal Printer User Instructions
1 General Information and Warnings 1.1 About this Manual This manual consists of user instructions to be used as a guide for printer installation and operation. Be sure to read all instructions before making any connections. The manual is divided into chapters by the chapter number and the large text at the top of a page. Subsections are labeled as shown by the 1 and 1.1 headings shown above. The manual name and page numbers appear at the bottom of the pages. 1.
1.3 Electrical Installation CAUTION: The power cable must be connected to an earth-grounded electrical outlet. The electrical supply must have a circuit breaker with an appropriate rating to protect from over-current conditions. IF IN DOUBT SEEK ADVICE FROM A QUALIFIED ELECTRICIAN. 1.4 Pluggable Equipment Pluggable equipment must be installed near an easily accessible socket outlet. 1.5 Wet Conditions The Model ZG310 printer is not a washdown unit. Do not install near water! 1.
1.8.1 Alternative Power Supply Arrangements The ZG310 is designed to be operated from a 9V to 36V voltage source that is capable of supplying the primary power for the printer.
1.11 EMC Caution System EMC compliance remains the responsibility of the system designer. It is recommended that screened cables are used; earthing arrangements will depend on the application.
2 Getting Started 2.1 Connections and EMC Precautions 2.1.1 Connector Details Two user connectors are provided as shown below: Power Supply Input Jack Socket Jack RJ12 Data Socket Figure 2.1 Connector view from rear of printer. 2.1.2 Connector Pinouts PSU Jack Socket Detail Pin Dimension (mm) Function Inner Inside Ø 2.1 Positive 9-36 VDC Input Outer Outside Ø 5.5 Negative / 0V Common The maximum insertion length is 12 mm.
RS232 Data Cable Configuration (9 pin): 2.2 D-9 Pin Name Function (refers to PC) ZG310 Pin 3 TxD Serial Data Output 3 2 RxD Serial Data Input 4 6&8 CTS & DSR Busy Input 5 5 SGND Signal Common 0V 6 Connecting to a PC 1. Make hardware connections. 1a. Be sure the PC has a D-type serial connector; otherwise, a serial to USB converter will need to be used. 2. Use any of the available serial ports of the ZG310. 3. Make sure that the power supply is switched on and connected.
2.2.1 Application Program Once communications between your computer and the printer have been established, you can try driving the printer from your application program. As referred to in the Programmers Guide, the ZG310 has a control code set based on the EPSON ESCPOS protocol. Many of the commands are as closely compatible as they can be, given the mechanical differences between printers, but if the application program was originally written for another printer, it may need to be modified.
3 Modes of Operation The ZG310 has two operating modes, when not actually printing: l Idle Mode: ready to accept data, but no data is in the buffer awaiting printing, and the printer motor is not running; l Spool Mode: active, but storing data for later printing. Modes are indicated by different color combinations on the front-panel LED (see page 12). The ZG310 is supplied configured as permanently powered on whenever the power supply is connected and switched on.
Table 3.1 LED Pattern Table Pattern Power Status Buffer Mode Constant Green OK Normal Fast Flashing Green OK Spool * Long Green - Short Red Low Voltage Normal Short Green - Short Red Low Voltage Spool * Error Condition Spool (Printing prohibited) Fast Flashing Red No light Printer is off * (Spool may have resulted from Paper Out or Head Up conditions) Although this table may seem complicated, few applications will produce many of the combinations.
4 Paper Pressing the paper feed button when the printer is idle, or in spool mode, advances paper at typically 50 mm per second. However, the feed button has additional functions: Double-clicking the button (i.e. pressing and releasing twice in quick succession just like a PC mouse): l l in idle mode, prints a demo/test message including the firmware version, encoded calibration data, and the full character set; in spool mode, or having been out of paper, prints any stored data and enters idle mode.
5 Printer Operation and Programming The ZG310 utilizes a Fujitsu FTP-628MCL103 printer mechanism, with a fixed (parallel) print head with 384 horizontally-arranged thermal elements. The paper is advanced by a stepper motor, and printing takes place in a single dot row for each step of the paper. Each printed dot is approximately 1/8 mm square. The printing speed and dot density are controlled according to the power supply voltage and the head temperature.
5.4 Graphics Printing and Other Programming Modes Various dot-addressable graphics modes are supported, at up to 384 dots per line. Refer to the Service Manual for full details of this and other advanced programming modes. 5.5 Interface Details 5.5.1 RS-232 Serial Interface The ZG310 printer has an industry standard RS-232 interface. The default parameters are 9600 baud, 8 data bits, 1 stop bit and no parity.
