FAQs

Can the printer encode RFID tags while printing the label?

Yes. Zebra RFID printer configurations include an integrated RFID encoding system that writes data to compatible RFID inlays during the print process. The printer can also identify unsuccessful RFID encoding operations, depending on the model and RFID configuration.

Can Zebra RFID printers print both barcodes and RFID labels?

Yes. Compatible Zebra RFID printers can print conventional barcode labels as well as RFID-enabled labels. The same printer can therefore be used for standard identification labels and RFID labels, depending on the media and printer configuration.

What print resolution should I choose: 203, 300 or 600 DPI?

The required resolution depends primarily on label size, barcode dimensions, text size and the level of detail required. 203 DPI is commonly suitable for general industrial and logistics labels, while 300 DPI provides greater detail for smaller text and graphics. 600 DPI is intended for applications requiring very fine print detail.

How should I select a Zebra RFID printer?

Selection of a Zebra RFID Printer should be based on required print resolution, print volume, label width, print speed, RFID media characteristics, connectivity, environmental requirements and the level of automation required. The printer should also be matched to the RFID inlay and label construction used in the application.
