Forms
A form contains data. This data is a sequence of self–contained commands
and text that can occupy one or more pages of the form. The data form can
be downloaded then stored in printer memory for later use. The status report
lists the form IDs loaded in the printer.
Once a form is downloaded, it is selectable. Stored data is merged with the
fill–in data stream, and the merged data is printed as a completed form.
When selected, the printed form can be printed repeatedly with different sets
of fill–in data.
Fill–in data is a sequence of commands and text, usually variable and not
repeated data, used to fill in the empty fields of a form. Each fill–in data field
is terminated with a switch character, as explained in the following section.
The fill–in data for the last field of a page must terminate with a switch
character unless it is the last page of a form. In this case, use the Terminate
Form sequence.
Forms and fill–in data conform to the following :
• Forms cannot be nested.
• Up to 32 forms can be loaded into the printer, subject to available
memory.
• Form size must not exceed 65K bytes.
• Each form page must terminate with FF (0/12) and have at least one
field.
• Do not use a form–feed character for fill–in data.
The following sections describe how to load a form into memory, select the
form for printing, terminate form generation, and delete the form from
storage.
