						SETTING COMMAND
[Name]	Set validation paper waiting time
[Format]	ASCII	ESC	f	t1	t2
	Hex	1B	66	t1	t2
	Decimal	27	102	t1	t2
[Range]	0 ≤ t1 ≤ 15
	0 ≤ t2 ≤ 64
[Default]	t1 = 0, t2 = 10
[Description]	Sets the time that the printer waits for validation paper to be inserted and the time from insertion of the
	validation paper to the start of printing.

•t1 specifies the wait time for validation paper to be inserted as [t1 × 1] minutes.

•When t1 is set to 0, the printer waits until validation paper is inserted.

•t2 specifies time from insertion of the validation paper to the start of printing as [t2 × 0.1] seconds.

[Notes]	■ The setting values for this command are used for validation paper insertion.
	■ When the waiting time t1 set by this command has passed, even though the validation paper is not
	detected, the printer ends the validation paper waiting state. Then the 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 paper.
	■ Waits for a validation paper to be inserted when the printer recovers from an error.
