WIF8 is ignored in
7-bit
mode. WIF5 must be 0 because WIF5 indicate Space
commands.
If no channels are specified in the FCB, the printer detects an error and
only prints,
it does not feed forms. Because commands X'OC' to
X'OF'
specify invalid channels, the printer detects then as errors.
(2) Space commands
Sopace
commands feed forms the specified number of lines after printing.
If data
WIFl
to WIF8 sent with the Paper Instruction signal is the same as
the that shown in Tables 4.6 and 4.7, the printer
(IFC
microprogram)
determines that the data indicates a Space command.
The relationship
between Space command data and the number of lines fed is shown in Tables
4.6
(15-line
feed mode) and 4.7
(63-line
feed mode).
