•
t1
specifies the wait time for validation paper to be inserted as [

seconds.
[Description]
•
The setting values for this command are used for validation paper insertion.
•
When the waiting time

set by this command has passed even though the validation

printer selects both paper sources - journal and receipt for printing. If data is in the print
buffer, the print data is printed on both journal and receipt.
