Forms Considerations
The following commands are not to be included in form data or fill–in data:
• Load a form, logo, or font
• Delete a form, logo, or font
• Invoke a Digital sequence
• Invoke a ESCc (RIS) sequence. This will exit you from the Form mode.
Be aware of the following conditions, which can affect the printer’s
output/performance in Forms mode:
• To minimize paper movement, print all text together and print all
graphics together. Most importantly, print all of the same density
material together.
• Encoded Escape sequences cannot start in the form and continue in the
fill–in data, nor can the reverse occur.
• Changes made to the font, cursor position, density, or mode are not
restored after you terminate a Form sequence.
• Block character used in a form must begin and end on the same page.
Form data switch characters and select form sequence switch characters
are not printable as block characters unless they are encoded.
• Since mode settings, fonts, and spacing parameters can be changed
between the time the form is loaded and the item it is selected, the
environment of the form (PUM or SSU) should be established in the
form data.
• If ESC, CAN, or SUB is embedded in the form string, it will terminate
form loading and the form will be discarded. Encoding DCS, RIS, CAN,
or SUB in a form string will also stop form loading.
• If the form length in the header does not agree with the length of the
form string received, the form is discarded.
• If the form is not terminated by a form feed (0/12), and does not contain
at least one form–switch character, a form–switch character and an 0/12
are added at the end of the form.
• In general, the number of switch characters in the form data should be
one more than the number of switch characters in the fill–in data.
