Validation Operation Control

The Series 150 Printer has several features that can be altered during operation. For example, the
time delay between when a form is sensed and when the form clamp is activated can be changed.
This allows the operation of the printer to be tailored to the application and the form being used.
All feature control commands are extensions of the [ESC] [EM] sequence. They are defined as
follows.

Validation clamp delay
[ESC] [EM] C <n>
1BH 19H 43H <n>
<27> <25> <67> <n>
&%ZC <m > <m >
1 2
[ESC] f
This command sets the clamp delay which is the time between when the
form is sensed and when it is clamped. (Only the least four bits are used.)
The default is configurable.
0 = 0 ms
1 = 50 ms
2 = 150 ms, and so on until
15 = 750 ms
Note: Once issued, the value will be used until the printer is power cycled
or the command is reissued.
Set validation time-out
[ESC] [EM] V <n>
1BH 19H 56H <n>
<27> <25> <86> <n>
&%ZV <m > <m >
1 2
[ESC] f
This command sets the time-out after a top validation command with
autosense is issued and the printer returns to receipt mode.
Where <n> is the delay in one minute increments; minimum is one
minute; maximum is 15 minutes. If <n> = 0, the delay is set to no time-out
(waits forever). The default is configurable.
