Triggering (Initiating) Printing
Triggering (initiating) of printing, depending on the state of the photo-detector, can take place in three
ways: through
Edge triggering
,
Level triggering 1
and
Level triggering 2
. The
Triggering
parameter can be used when the setting of the
Text repetitions
parameter ranges from 1 to 20. If
Text repetitions
=
Continuous
, the printer starts printing after the
PRINT ON/OFF
button has been
pressed and continues printing uninterruptedly without checking photo-detector signals.
The below description refers to the configuration of print parameters where text buffering is disabled
(the
No buffering
field in the
Parameters 3
tab sheet of the control program is ticked).
A) If the
Edge triggering
parameter is selected, then printing starts after the
exposed/ shaded
pulse edge (or
shaded/exposed
pulse edge, depending to the photo-detector operation mode
described on page
) has been detected.
The printer checks the photo-detector signal after the last print has been made in the iterative
printing mode (
Text repetitions
=2,…,20). If a pulse edge is detected, it repeats printing.
Example for
Text repetitions
=2
Fig. 3.3.10.3.
Example for
Text repetitions
=3
Fig. 3.3.10.4.
B) If the
Level triggering 1
parameter is selected, then printing starts after the appropriate photo-
detector signal level is detected (that means, the photo-detector is
shaded
or
exposed
). The
printer checks the photo-detector signal after the last print has been made in the iterative printing
mode. If the signal level is the same, the printer repeats printing. The level may change during
printing but this does not affect printing – text is printed the set number of times.
Example for
Text repetitions
=2
Fig. 3.3.10.5.
Example for
Text repetitions
=3
Fig. 3.3.10.6.
C) If the
Level triggering 2
parameter is selected, then printing starts after the appropriate photo-
detector signal level is detected. The printer checks the photo-detector signal constantly. If the
level has not changed, it prints successive texts. If it has, the printer stops printing. When the
signal is restored, the printer resumes printing from the place where the printing was interrupted.
Example for
Text repetitions
=2
Fig. 3.3.10.7.
The parameter is available in the
Advance
tab sheet after the
Adv. options
box has been ticked.
