Form Feed Form Feed <FF>:
Prints the data in the buffer, advances the paper
position to the next top-of-form and moves the character position to
the first character column. The FF code cancels all single-line only
print attributes.
Format
<FF>
Decimal: 12
Hex: 0CH
BASIC: CHR$(12);
Indeterminate Conditions
Forms length can be modified by using the control panel or forms
length control codes.
The Form Feed command may reacts differently if a VFU is active
(refer to VFU section).
Line Feed Line Feed <LF>:
Prints the data in the buffer (if any) and advances
the vertical character position one line at the current line space
setting and moves the logical print position to the left margin.
The LF function cancels all single line print attributes such as double
high (elongated) and double wide (expanded) characters.
In the Even Dot Graphics Plot mode (high density graphics), the LF
code does not cause paper position motion; the data in the buffer is
plotted and the logical print position is set at character column 1 in
anticipation of the Odd Dot Plot control code to complete high density
graphic plotting. In the Odd Dot Graphics Plot mode (normal density
graphics), the LF code plots the data in the buffer, advances the
paper position a single dot row at the current vertical dot density,
and positions the logical print position at character column 1.
