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 40 ) 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

Example for Text repetitions =3

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

The parameter is available in the Advance tab sheet after the Adv. options box has been ticked.
