Operation & OptionsThis section helps you get the most from your printer.You must use programming to control many of the printer’s functions. Afew examples:■The~JLcommand controls label length.■The^XA^MTD^XZcommand changes the printing mode to directthermal; the^XA^MTT^XZcommand changes the printing mode tothermal transfer.■The^XA^JUS^XZcommand saves the new settings to flash memory.For detailed information about creating labels using ZPL II, refer to the ZPLII Programming Guide or visit our web site at www.zebra.com.To improve print quality, changing both print speed and density may berequired to achieve the desired results. Your application’s printer driverprovides control of the speed and heat (density).Thermal PrintingThe print head becomes hot while printing. To protect from damaging theprint head and risk of personal injury, avoid touching the print head. Useonly the cleaning pen to perform maintenance.The discharge of electrostatic energy that accumulates on the surface of thehuman body or other surfaces can damage or destroy the print head orelectronic components used in this device. You must observe static-safeprocedures when working with the print head or the electronic componentsunder the top cover.You must use the correct media for the type of printing you require. Whenprinting without a ribbon, you must use direct thermal media. When usingribbon, you must use thermal transfer media. The printer’s ribbon sensordetects motion of the supply spindle.980476-001A 21
Replacing SuppliesIf labels or ribbon run out while printing, leave the printer power on whilereloading (data loss results if you turn off the printer). After you load a newlabel or ribbon roll, press the Feed button to restart .Always use high quality, approved labels, tags and ribbons. If adhesivebacked labels are used that don’t lay flat on the backing liner, the exposededges may stick to the label guides and rollers inside the printer, causing thelabel to peel off from the liner and jam the printer. Permanent damage to theprint head may result if a non-approved ribbon is used as it may be woundincorrectly for the printer or contain chemicals corrosive to the print head.Approved supplies can be ordered from your dealer.Adding a New Transfer RibbonIf ribbon runs out in the middle of a print job, the indicator lights red andthe printer waits for you to add a fresh roll.1. Keep the power on as you change ribbon.2. Open the top cover, then cut the used ribbon so you can remove thecores.3. Load a new ribbon roll. If necessary, review the Ribbon Loading steps.4. Close the top cover.5. Press the Feed button to restart printing.Replacing a Partially Used Transfer RibbonTo remove used transfer ribbon, perform the following steps.1. Cut the ribbon from the take-up roll.2. Remove the take-up roll and discard used ribbon.3. Remove the supply roll and tape the end of any fresh ribbon to preventit from unwrapping.When reinstalling a partially used supply roll, tape the cut end onto theempty take-up roll.22 980476-001A
Printing in Peel-ModeThe optional dispenser allows youto print in “peel-mode” where thelabel backing follows a different path andthe labels are presented one at a time forsubsequent placement.Before using peel-mode, you must sendthe programming commands^XA ^MMP ^XZ^XA ^JUS ^XZto the printer. Refer to your ZPL IIProgrammer’s Manual.1. Remove several labels from thebacking material.2. Open the top cover.3. Open the dispenser door.4. Switch on the label-taken sensor.5. Insert the backing in front of the peelbar and behind the peel roller.6. Close the dispenser door.7. Close the top cover.8. Press the Feed button to advance thelabel.During the print job, the printer will peeloff the backing and present a single label.Take the label from the printer so it willprint the next label.980476-001A 23ON OFFMOVIE
Printing on Fan-Fold MediaPrinting on fan-fold media requires you toset both the media hangers and the mediaguides in position.1. Open the top cover.2. With a sample of your media, adjustthe media hangers to the width of themedia. The hangers should just touch,but not restrict, the edges of themedia.3. Tighten the screw using a smallPhillips driver #1.4. With a sample of your media, adjustthe guides to the width of the media.The guides should just touch, but notrestrict, the edges of the media.5. Insert the media through the slot at therear of the printer.6. Run the media between the hangersand guides.7. Close the top cover.24 980476-001ALock-downScrew
RFID GuidelinesThe Zebra R2844-Z Smart Label Printer and Encoder serves as dynamictool for both printing and programming smart labels and tags. These labelsand tags are usually made from two components, media and an RFID (radiofrequency identification) transponder.■The media is comprised of synthetic- or paper-based material that can beprinted upon using direct thermal or thermal transfer printing techniques.The media is typically made from the same materials and adhesives usedby a standard barcode printer.■The transponder is usually comprised of an antenna coil that is bondedto an integrated circuit (IC) chip. The IC contains the drivers, coders,decoders and memory. At a minimum, the transponder has memory thatcan be read, while the vast majority also have memory that can beprogrammed by the user as well.980476-001A 25MediaSupplyMedia TransponderOutline oftransponder(shape variesby manufacturer)LinerMedia Transponder
The communication between the RFID tag and the printer is establishedwhen the transponder lines up with the printer’s antenna.Note • The transponder position, prior to encode/decode, is critical. The optimaltransponder position varies with antenna coil size and type of RFID IC used. It isimportant to use media and tags that have been specifically designed for use in thisprinter. Failure to do so may result in the inability to read or program the embeddedRFID tags.Printing and programming of smart labels is handled through the use ofZebra's printer programming language, ZPL. The printer segments thereceived ZPL's RFID-specific and printing-related commands. The printerwill execute the RFID commands first, followed by those for printingbarcodes and text. Each transponder has blocks of addressable memory thatare written to and read from through ZPL commands. Many transpondersalso contain a pre-programmed unique ID/serial number. The ZPLcommands also provide for exception handling, such as setting the numberof read/write retries before declaring the transponder defective.26 980476-001AMediaSupplyRibbonSupplyRibbonTake-upTranspondersimbeddedin mediaAntennaReader/WriterBoardBracket
If an RFID tag is declared defective (fails to program correctly or cannot bedetected) the printer ejects it and prints the word "void" across the entirelabel (see samples on page 45). If problems persist, this process—using thesame data and format—will continue from one to ten tags; you set theretries using a parameter in the RFID Setup command (^RS). After the lasttag is ejected the printer removes the customer format from the print queue,and proceeds with the next format (if one exists in the buffer).Print Quality Over the TransponderThere is a raised area on each label immediately around the location of theIC chip where the printer may print with low quality.Design your printed label around the location of the chip in the type ofapproved smart label you select. For best results, do not print barcodesdirectly over the transponder. If in doubt, check the print quality and adjustthe label format, or obtain smart labels with an alternate transponderplacement.980476-001A 27Top ViewProfile
Supported TranspondersUse transponders specifically approved for use in the R2844-Z printer.Failure to do so may result in the inability to read or write to imbeddedRFID tags. For a current list of approved transponders, contact ZebraTechnologies Corporation or visit the website (http://www.rfid.zebra.com).As new transponders become commercially available, Zebra will evaluatethem for compatibility with the R2844-Z printer.Important • Function of an encoded smart label in an application depends on factorssuch as where the label is placed on an item (such as a carton or a pallet) as well ason the contents of the items (such as metals or liquids). Contact the supplier of yourexternal RFID reader for assistance with these types of issues. Zebra can onlysupport issues regarding printing and encoding smart labels.28 980476-001A
Transmission and Identification StandardsISO-15693ISO-15693 is an international standard for 13.56 MHz RFID devices. Asthis is a public standard, tags and integrated circuits may be produced by awide variety of manufacturers. The current standard stipulates thatmanufacturers may configure memory in various ways (up to 256 blockscomprising a block size up to 256 bits (32 bytes)). The standard alsostipulates that a manufacturer may, or may not, use the recommendedmethods of reading and writing to the tag as stipulated in the standard. Forthese reasons, the printer may not be compatible with every manufacturer'sISO-15693 transponders. Contact your technical support representative forthe latest list of supported ISO-15693 transponders.For more information, see the International Standards Organization website at:http://www.iso.orgElectronic Product Code™ (EPC™)The Electronic Product Code™ (EPC™) is a product numbering standardthat can be used to identify a variety of items using RFID technology. TheEPC format contains 12-bytes (96-bits) of data defining the manufacturer,product, and serial number. The EPC can link to an online database,providing a secure way of sharing product-specific information along thesupply chain.For more information, see the EPCglobal web site at:http://www.epcglobalinc.org980476-001A 29

ZPL II Commands for RFIDValid programming requires that printer instructions begin with the StartFormat command (^XA) and finish with the End Format command (^XZ);they are the opening and closing brackets, respectivley, of a label formatinstruction.This subsection describes the RFID-related commands:■^WT – Write Tag■^RT – Read Tag■^RS – RFID Setup■^RI – RFID Get Tag ID■^RE – Enable/Disable Electronic Article Surveillance Bit36 980476-001A
^WT – Write TagThe format for the ^WT instruction is:^WTb,r,m,w,f,vwhere the parameters are:b = block numberDefault value: 0Other values: 1 to n, where n is the maximum number ofblocks for the tagThis is the starting block number. If the user sends more than a block of data itwill overflow into the next block. If the user overflows the block andsubsequent blocks cause errors (write protects, beyond range, etc.), the writewill be aborted, but blocks already written will not revert to original contents.It’s up to the user to ensure blocks aren’t accidentally overwritten.r = retriesDefault value: 0Other values: 1 to 10, number of retriesm = motionDefault value: 0 (Feed label after writing)Other value: 1 (No Feed after writing, other ZPL may causea feed)w = write protectDefault value: 0 (NOT write protected)Other value: 1 (Write protect)f = data formatDefault value: 0 (ASCII)Other value: 1 (Hexadecimal)v =Not used for this printer.If there is an error within the data for the transponder, the printer actsaccording to the error handling parameter of the RFID Setup command(^RS).980476-001A 37
^RT – Read TagThe format for the ^RT instruction is:^RT#,b,n,f,r,m,swhere the parameters are:# = number to be assigned to the fieldDefault value: 0Other Values: 1 to 9999b = starting block numberDefault value: 0Other values: 1 to n, where n is the maximum number ofblocks for the tagn = number of blocks to readDefault value: 1Other values: 2 to n, where n is maximum number of blocksminus starting block number. In other words, if the tag has 8blocks (starting with block 0) and you’re starting with block 6,n can be 2. This would give you block 6 and block 7information.f = formatDefault value: 0 ASCIIOther value: 1 Hexadecimalr = retriesDefault value: 0Other values: 1 to 10, number of retriesm = motionDefault value: 0 (Feed label after writing)Other value: 1 (No Feed after writing, other ZPL may causea feed)s =Default value: 0 (Least Significant Byte first)Other value: 1 (Most Significant Byte first)38 980476-001A
^RT – Read Tag (continued)Example: This reads a block from a tag, and prints it on a label:^XA^RS1,0^FS^FO20,120^A0N,60^FN1^FS^FO20,100^A0N,20^FN2^FS^RT1,7,3,0,5,0,0^FS^RT2,2,2,0,5,0,0^FS^XZThe first ^RT command automatically detects the tag type, starting at block7, reads three blocks of data in ASCII format. It will retry the command 5times if necessary. A “void” label will be generated if the read isunsuccessful after ‘r’ retries. The data read will go into the ^FN1 locationof the recalled format.The second ^RT command automatically detects the tag type, starting atblock 2, and reads two blocks of data in ASCII format. It retries up to 5times. The data read will go into the ^FN2 location of the recalled format.You can send data back to the host with the Host Verification command(^HV). Refer to the ZPL II manual to learn about this command.980476-001A 39
^RS – RFID SetupUse this command to set up RFID operation and error handling. You canmove the tag into an effective area to read or write.The format for the ^RS instruction is:^RSt,p,v,n,ewhere the parameters are:t = tag typeDefault value: 1 –Auto Detect (automatically determine thetag type, by querying the tag)Other values:2- Texas Instruments Tag-it™ tags3- Philips I•Code tags4- Inside Technologies Picotag® 2K5- ISO 15693 tag (see note)6- EPC Tag (13.56 MHz)p = read/write position of a transponder in vertical (Y-axis) indot-rows from the top of the label.Default value: label length minus eight dot-rowsOther values: zero to label lengthSet to zero ( 0 ) so that the media will not move; that is, thetransponder is already in the effective area.v = length of void print out in vertical (Y-axis) dot-rows.Default value: label lengthOther values: zero to label lengthn = number of labels to try in case of read/encode failureDefault value: 3Other values: 1 to 10, number of labelse = error handlingDefault value: 'N' (no action)Other values:'P'- printer pauses'E'- printer goes into error mode40 980476-001A
^RS – RFID Setup (continued)If the read/encode retries exceed the number set by the "n" parameter, anerror will be sent to the host as an unsolicited message. To control theunsolicited message, use the ZebraNet Alert commands (^SX and ^SQ) andset the "condition type" parameter to "P."Note • Use caution when using this function in combination with ^RI (reading theunique ID number) or ^RT (reading tag data). Problems can occur if the data readfrom the tag is going to be printed on the label. Any data read from the transpondermust be positioned to be printed above the read/write position. Failure to do this willprevent read data from being printed on the label or tag.980476-001A 41
^RI – RFID Get Tag IDThe format for the ^RI instruction is:^RI#,f,r,mwhere the parameters are:# = field number to store the unique IDDefault value: 0Other values: 1 to 9999f = formatDefault value: 0- MSB first for ISO15693. LSB first inother tags.Other vlaue: 1- LSB first for ISO15693. MSB first inother tags.r = retriesDefault value: 0Other values: 1 to 10, number of triesm = motionDefault value: 0 (feed)Other value: 1 (no feed)The printer reads the ID from the tag so that it can be printed or returned tothe host by using the Host Verification command (^HV).42 980476-001A
^RI – RFID Get Tag ID (continued)The example below reads the unique ID/serial number from a tag, andprints it on a label:^XA^FO100,100^A0N, 60^FN0^FS^RI0^FS^FD ^FS^XZ980476-001A 43
^RE – Enable/Disable Electronic Article Surveillance BitUse this command to set the Electronic Article Surveillance (E.A.S.) bit.This command has no effect on transponders (such as the Texas InstrumentsISO 15693) that do not support E.A.S. capabilities.The format for the ^RE instruction is:^REt,rwhere the parameters are:t = set the E.A.S. bitDefault value: 'n' (Disable E.A.S.)Other value: 'y' (Enable E.A.S.)r = retriesDefault value: 0Other values: 0 to 10, number of retries44 980476-001A
RFID Programming ExamplesZPL IITM is Zebra Technologies Corporation’s Zebra ProgrammingLanguage II label design language. ZPL II lets you create a wide variety oflabels from the simple to the very complex, including text, bar codes, andgraphics.This subsection is not intended as an introduction to ZPL II. If you are anew ZPL II user, order a copy of the ZPL II Programming Guide or go tothe internet address http://support.zebra.com and select the DocumentationButton to download the guide.980476-001A 45
Sending ZPL Commands to the PrinterFor your programming, do the following:1. Set up the printer and turn the power on.2. Use any word processor or text editor capable of creating ASCII-onlyfiles (for example, Microsoft Word® and save as a .txt file) and type inthe label format exactly as shown in the sample label format thatfollows.3. Save the file in a directory for future use. Use the “.zpl” extension.4. Copy the file to the printer.From the DOS command window, use the “COPY” command to send afile to the Zebra printer. For example, if your file name is format1.zplthen type, “COPY FORMAT 1.ZPL XXXX”, where “XXXX” is theport to which your Zebra printer is connected, for example, “LPT1.”5. Compare your results with those shown. If your printout does not looklike the one shown, confirm that the file you created is identical to theformat shown, then repeat the printing procedure. If nothing prints,refer to the “Getting Started” on page 7 to make sure your system is setup correctly, otherwise refer to the “Troubleshooting” on page 61.46 980476-001A
