Method

The machine features a wheel with raised characters, similar to a daisy wheel

Daisy wheel printer

Daisy wheel printers use an impact printing technology invented in 1969 by David S. Lee at Diablo Data Systems. It uses interchangeable pre-formed type elements, each with typically 96 glyphs, to generate high-quality output comparable to premium typewriters such as the IBM Selectric, but two to...

. The user turns the wheel to align the desired character with the tape and presses a trigger, forcing the character against the tape. Upon releasing the trigger a mechanism advances the tape to the next position. The embossed characters stand out from the tape and look white due to stretching of the plastic.

The tape is more rigid than most other labeling materials, and may come loose if the labeled object bends or under the force of its original curvature, if the label is not straightened after being printed.
