Print Media Types

Your printer can use various types of media.

Zebra strongly recommends that you use Zebra-brand supplies for continuous high-quality printing. A wide range of paper, polypropylene, polyester, and vinyl stock has been specifically engineered to work with your printer for optimal results and prevent premature printhead wear. To purchase supplies, go to zebra.com/supplies.

These types of media can be used with your printer:

Standard media—Most standard (non-continuous) media uses an adhesive backing that sticks individual labels or a continuous length of labels to a liner.

Continuous roll media—Most continuous roll media is direct thermal media (similar to fax paper) and is used for receipt or ticket style printing.

Tag stock—Tags are usually made from heavy paper (up to 0.0075in./0.19mm thick). Tag stock does not have adhesive or a liner, and it is typically perforated between tags.

The printer typically uses roll media, but you can use fanfold or other continuous media too. Use the correct media for the type of printing you require. You must use direct thermal media.

Roll and Fanfold Media Types
Media Type	How It Looks	Description
Non-continuous roll media		Roll media is wound on a core that can be 12.7 to 38.1 mm (0.5 to 1.5 in.) in diameter. Labels have adhesive backing that sticks them to a liner, and they are separated by gaps, holes, notches, or black marks. Tags are separated by perforations. Individual labels are separated by one or more of the following methods: Web media separates labels by gaps, holes, or notches. Black mark media uses pre-printed black marks on the backside of the media to indicate label separations. Perforated media has perforations that allow the labels or tags to be separated from each other easily. The media may also have black marks or other separations between labels or tags. Perforated media has perforations that allow the labels or tags to be separated from each other easily. The media may also have black marks or other separations between labels or tags.
Non-continuous fanfold media		Fanfold media is folded in a zigzag pattern. Fanfold media can have the same label separations as non-continuous roll media. The separations would fall on or near the folds.
Continuous roll media		Roll media is wound on a core that can be 12.7 to 38.1 mm (0.5 to 1.5 in.) in diameter. Continuous roll media does not have gaps, holes, notches, or black marks to indicate label separations. This allows the image to be printed anywhere on the label. A cutter can be used to cut apart individual labels. With continuous media, use the transmissive (gap) sensor so the printer can detect when the media runs out.
