Printing with Android Devices Introduction

Zebra Terminology • ZPL – Zebra Programming Language, one type of programming language utilized by Zebra printers. This is the

recommended development language. Other languages are EPL, CPCL and Line Print.

• ZPL Command: An instruction sent to the printer to configure the printer, print label (formats/templates),and get device status information (ex. ^B8 command prints a EAN-8 bar code).

• ZPL Format : One time send (all of the data is sent together) of a static form built with ZPL code to be printed or downloaded into the printer.

• ZPL Template: A dynamic form built with ZPL code to be downloaded into the printer that adds variable data fields.

• Recall ZPL Template: Prints by dynamically allocating values to variables in a ZPL template previously downloaded to the printer.

• ZPL RFID Command: In addition to reading or encoding RFID tags, the RFID ZPL commands also provide for RFID exception handling, such as setting the number of read/write retries before declaring a transponder defective (set with ^RR, ^RT, and ^WT) or setting the number of labels that will be attempted if an error occurs (set with ^RS).

• SGD Command (Set, Get, Do): An instruction sent to the printer to set or get configuration details (ex. configure the printer language). These commands allow a user to configure printers with firmware versions V60.15.xZ, V50.15.xZ, V61.15.xZ, V56.15.xZ, V53.15.xZ, or later. The printer performs the specified function immediately after receiving the command. Commands are case sensitive. The 3 types of commands are: setvar, getvar and do. Ex. ! U1 setvar “device.languages” “zpl”

• Zebra's Best Practices Document: A document outlining Zebra’s recommendations on how to build a best in class application. It includes minimum functional requirements and best.

Zebra’s Best Practices

6

6

• Printer does not need special set up to work with app

App interfaces with printer out of the box

• The app will not freeze, lockup, or crash when interacting with the printer such as attempting to communicate with the printer and encountering the common error cases listed below.

• Printer unreachable by the client.

• Printer is out of media.

• Printer media door is left open.

Stability 稳定性

• The app produces the expected printed output with acceptable print quality.

Printed Output 打印输出

• The application will check and set the language of the printer (ZPL, Line Mode, CPCL, etc.).

Check Printer Formatting Language 检查打印机语言

• The application will check the status of the printer before sending a print-job. Once the printer verifies the printer is not in an error state, the print job can be sent.

Check Printer Status 检查打印机状态

• All apps must alert the user if the printer is unreachable or in any other error states before sending a print job. The app should be specific about the error state that the printer is in. ie. Out of paper, door open, etc.

Display Printer Error Status 显示打印机的错误信息

• Verify that, if present, usage of Zebra printer branding (logo, model number, etc.) meets Zebra Technologies Global Brand Standards.

Proper Zebra Branding 适当使用斑马的标志

Zebra’s Best Practices

• New functionality and features are being focused exclusively on ZPL.

Use ZPL for label formatting

使用ZPL去构建标签格式

• Graphic data is generally larger file size. It also introduces risk of distortion & unreadable barcodes.

• Static images, such as logos, should be stored in printer memory and recalled at time of print.

Print Graphics Only When Necessary

仅仅只当需要的时候才去打印图片

Concepts of Printing with Zebra

Devices

Concepts of Printing with Zebra Devices - Connectivity

• Set up Connectivity /Discovery • Bluetooth (3.0/4.0) • WIFI (802.11a/b/g/n) • NFC (Except for Apple)

WLAN connectivity supports both 2.4GHz and 5GHz bands and roaming within and across bands.

The multiport radio can simultaneously operate 802.11a/b/g/n and Bluetooth 3.0

Print Touch enables new experiences and quick access to helpful information. Print Touch devices offer app and web page launching features

Concepts of Printing with Zebra Devices – Common Use Cases • Send “ZPL format to print”

• Print of a Image (JPG/PNG) • Select an image on Mobile Device • Send to print image selected

• Signature Capture – Dynamic capture of signature on

Android Device

– Send image of signature to print

• Receipt – Input Data

– Dynamic addition to ZPL format – Send to print

• Store Format – Selecting ZPL file

– Store ZPL file in Zebra Printer
