3.5 Text printing
3.5.1
Printing priorities
As well as the traces of the chart, the recorder can also print text. Text printing
is used to make comments on the traces and for recording events. The char-
acters are printed in dots in a 7 x 9 matrix.
There are different kinds of text which can have priorities and a printing mode
assigned to them by the setup program. These priorities determine the criteria
for interruption or cancellation when more than one text print is required at the
same time.
For all the following explanations, the rule is:
- Text 1 = text with higher priority
- Text 2 = text with lower priority
If Text 2 is being printed when a request for Text 1 appears, then the printing of
Text 2 is abandoned and Text 1 is printed. The abandoned text will not be con-
tinued and not repeated.
If a request for Text 2 occurs while Text 1 is being printed, then Text 2 will be
printed out after Text 1 has been printed.
Example:
A report is printed from 12:00 to 12:05 with high priority. At 12:02 a limit is ex-
ceeded, so the corresponding text should be printed out. Since printing this
text is not possible at the moment, the text will be printed after the report is
finished.
