Loading Roll Media

All of the ZD620 and ZD420 4 inch Link-OS printers load print media rolls the same.

The printers support the three basic types of media:

Continuous (receipt, etc.) with no marks to define print length.

Marked media (black lines, black marks, notches, or holes) to define print length

Label media that uses the sensor to look through the media backing (liner) to see the beginning and end of labels on the roll.

The printer utilizes two sensing methods to accommodate a wide range of media:

Center-area transmissive sensing for continuous media and gap/web label media.

Full-width movable (reflective) sensing for print format (length) using black marks, black lines, notches, or holes.
