Functional Description 2-16
Controls the paper feed on the selected device.
If the printer is in ON LINE and paper is present:
-with manual or ASF feed and data to be printed in the
buffer, but waiting for a Form Feed command, it forces the
print of an unconcluded page and its ejection;
-with Sprocket paper feed and data to be printed in the buffer
but waiting for a Form Feed command, it forces the print of
an unconcluded page and feeds the continuous module to the
next first print position (TOF).
If the printer is in LOCAL and paper is present:
-with manual paper feed or ASF the sheet is ejected.
-with Sprocket it feeds the continuous module as far as the
next first print position (TOF).
If there is no paper in the printer, regardless of the operating
status:
-in manual paper feed or ASF it tries to insert a sheet in the
printer
-with Sprocket it tries to feed the continuous module as far as
the first print position (TOF).
With the machine in ON LINE mode and without data to be
printed (empty buffer) or in LOCAL mode, it advances the
paper by one elementary unit (1/150").
Keeping the key pressed the paper continues to advance until
the key is released.
Keeping these two keys pressed at machine power on the first
file that is transmitted to the printer will be interpreted as a
configuration file (see section 8.3).
