21 1 Introduction This guide is the unabridged, alphabetical reference of programming commands supported in the firmware. Firmware You can get the printer s firmware version by printing out a configuration label. For instructions to do so, see your printer s user guide. Note Firmware upgrades are available at: If you are using a previous version of Zebra printer firmware, some of the commands are the same and function as they did before but equally as many are new and are not recognized by firmware earlier than X.10. Many word processors or a text editor capable of creating ASCII files can be used to recreate most examples in this guide. However, for other encodings such as Unicode, a text editor such as Microsoft Notepad is needed. If there are any terms used in this guide that you need clarification on, please see the Glossary on page /15/06 ZPL II Programming Guide 45541L-004 Rev. A

23 2 ZPL Commands This section contains the complete alphabetical listing of ZPL II commands. Description This heading provides an explanation of how the command is used, what it is capable of, and any defining characteristics it has. Format Format explains how the command is syntactically arranged and what parameters it contains. For Example The ^B8 command prints a EAN-8 bar code. The format of the ^B8 command is: ^B8o,h,f,g. It is arranged with the caret symbol (^), the command code (B8), and the parameters and are replaced with supported values. Parameters If a command has values that can be defined to make its function more specific, these are outlined as parameters. Parameters typically have Accepted Values and Default Values. Still using the ^B8 example, the h parameter is defined as: h = bar code height (in dots) Accepted Values: 1 to Default Value: value set by ^BY If the command has no parameters for example ~JA (Cancel All) the parameter heading is removed, indicating that the format of the command (~JA) is acceptable ZPL II code. 9/15/06 ZPL II Programming Guide 45541L-004 Rev. A

24 4 ZPL Commands Example When the command is best clarified in context, an example of the ZPL II code is provided. Text indicating exact code entered is printed in an easily recognizable Courier font. An example of code using the ^B8 command looks like this: ^XA ^FO50,50 ^B8N,100,Y,N ^FD ^FS ^XZ Notice that the ^B8 parameter letters have been replaced with real values that apply to the command. In this example N,100,Y,N have been entered. Comment This section is reserved for notes that are of value to a programmer, warnings of potential command interactions, or command-specific information that should be taken into consideration. Example An example comment is: This command works only when the printer is idle, or This command is ignored if a value exceeds the parameter limits. Comments are also included next to parameters if they apply directly to a particular setting L-004 Rev. A ZPL II Programming Guide 9/15/06

25 ZPL Commands Basic ZPL Exercises and Examples 5 Basic ZPL Exercises and Examples The purpose of these exercises is to introduce basic ZPL commands to novice ZPL users. Make sure this checklist is complete: Tips Load the printer with labels that are big enough to give you ample space to work with. Print a configuration label (CANCEL test). Look at the configuration label and make sure that the LEFT POSITION is set to 000 and LABEL TOP is set to 000. Determine the printer s resolution. It is listed on the configuration label. 8/MM = 200 dpi, 12/MM = 300 dpi and 24/MM = 600 dpi. These are some tips when using ZPL: Use the DOS text editor to write ZPL files. Save the file as a.txt file and copy it to the printer from DOS command line. Before You Begin Some things that are important to understand before you begin are: 200 dpi means the resolution of the printhead is 200 dots per inch. If you program the printer to draw a line 100 dots long that equals a half inch. 100 dots on a 300 dpi printer prints a line 1/3 inch long. The home position that all your coordinates are referencing is at the left-hand trailing edge of the label as the label comes out of the printer. (There are some exceptions to this.) Exercises The exercises start simple and gradually progress to give you an opportunity to try a variety of commonly used ZPL commands. Not all commands are covered, but this should be a good core of commands to learn. Some commands may not be supported due to the firmware version in your printer. 9/15/06 ZPL II Programming Guide 45541L-004 Rev. A

26 6 ZPL Commands Basic ZPL Exercises and Examples Exercise 1 This exercise shows you how to specify a location for an entered name. 1. Print your name on the label. 2. Start by printing just your name on the label. Use this format as a model: Important Your name goes where you see xxxxxxxxxxx in the second line of code. 3. Send this format to the printer: ^XA ^FO50,50^ADN,36,20^FDxxxxxxxxxxx ^FS ^XZ 5 1 Every format starts with the ^XA command 2 ^FO (field origin) command 3 ^FS (field separator) command 4 Every format ends with the ^XZ command 5 ^FD (field data) command 4. When the label prints correctly, alter the first number after the ^FOx. See how that change affects the print position. Alter the second number after the ^FO50,x and see how that the print position. Font instruction ^ADN 1. Alter the numbers after the ^ADN,x,x command. 18,10 is the smallest size you can make the D font. The first number is the height of the font in dots. The second number is the width in dots. You can use direct multiples up to ten times that size as a maximum. Example 180,100 is the largest you can make the D font. 25,18 would not be a valid size. The printer rounds to the next recognizable size. 2. Check the font matrices tables for other fonts to try. See Fonts and Bar Codes on page Try the zero scalable font ^A0N,x,x. This font is scalable, and you can choose any height and width L-004 Rev. A ZPL II Programming Guide 9/15/06

27 ZPL Commands Basic ZPL Exercises and Examples 7 Rotation commands 1. Change ^ADN to ^ADR, and then ^ADI, and then ^ADB. See how the print position changes. 2. Add more fields. 3. Add two more fields to print directly under your name using the ^ADN,36,20 font and size: Your street address Your city, state, zip 4. You must add two more lines of code that start off with: ^XA ^FO50,50^ADN,36,20^FDxxxxxxxxxxx^FS ^FO (fill in the rest) ^FO (fill in the rest) ^XZ Make sure all these fields print in the same font and size and left side of fields has same vertical alignment. Your name 1200 W Main Street Anytown, Il Exercise 2 Boxes and lines 1. Use the address format from Exercise Add this new line to your existing format: ^FO50,200^GB200,200,2^FS This prints a box one wide by one inch long and the thickness of the line is 2 dots. 3. Reposition and resize the square so that it goes around the name and address uniformly. 4. Print a line by adding: ^FO50,300^GB400,0,4,^FS This prints a horizontal line two inches wide by 4 dots thick. 5. Print a vertical line using this code: ^F0100,50^GBO,400,4^FS 9/15/06 ZPL II Programming Guide 45541L-004 Rev. A

28 8 ZPL Commands Basic ZPL Exercises and Examples Exercise 3 Bar codes ^B3 code 39 bar code 1. Write the following format and send to the printer: ^XA ^FO50,50^B3N,N,100,Y,N^FD123456^FS ^XZ 2. Try changing each of the parameters in the ^B3 string so you can see the effects. Important For valid parameter choices, see ^B3 on page 22. ^B3o,e,h,f,g ^BY 3. Insert the ^BY command just before the ^B3 to see how the narrow bar width can be altered. ^FO50,50^BY2^B3..etc ^BYx, acceptable values for x are 1 through Alter the ratio of the narrow to wide bar. ^FO50,50^BY2,3^B3..etc ^BY2,x acceptable values for x are 2.1 through 3 in.1 increments 5. Print out a ^B3 bar code with the interpretation line on top of the bar code and the bar code rotated 90 degrees. 6. Add a ^PQ just before the ^XZ to print several labels. ^PQ4 ^XZ ^PR Print rate (in inches per second) 7. Add a ^PR command after the ^XA at the beginning of the format to change the print rate (print speed). ^XA ^PR4 then try ^PR6 ^PRx acceptable values for x are 2 through 12 (check printer specs) See how the print speed affects the print quality of the bar code. You may need to increase the printer darkness setting at higher print speeds L-004 Rev. A ZPL II Programming Guide 9/15/06
