Do vvpat have programmatic backfeed? Not manual. But can inside program issue command to implement backfeed?
.
ChatGpt says : Most likely yes — at least at the firmware/mechanism level, the VVPAT printer controller almost certainly can issue some kind of reverse-feed/backfeed motor command internally.

Reasoning:

* Thermal printer mechanisms commonly support bidirectional paper control for:

alignment,
calibration,
cutter positioning,
Jam recovery,
sensor synchronization.

* The VVPAT uses:

optical paper-position sensing,
black mark detection,
controlled paper presentation timing,
automatic paper loading/alignment.

Those functions are usually easier if the firmware can command the stepper motor both forward and backward in small increments.

So technically, inside the embedded firmware, there is very likely .....
