Chapter 6 — Retrieving and Printing a Form
34
Once a form has been retrieved, it can be used over and over
again until another form is retrieved. All variable input data and
counter values are stored in the volatile memory, which means it
is lost when the printer loses power. If prompts are enabled,
existing data and counter values are displayed on the screen after
the related prompt. Any input data can be overwritten at will.
