ESC v

[Function] Sends Paper Sensor Status

[Code] ASCII ESC v

Hexadecimal 1B 76

Decimal 27 118

[Outline] This command sends the status of the paper sensor when it is executed.

[Caution] The following table describes the status sent.

• If DTR/DSR control is selected and the memory switch 4-5 is set to 0, the printer sends only

1 byte after conﬁrming that the host is ready to receive (the DSR signal status is Space).

If the host is not ready (the DSR signal status is Mark), the printer will wait until it will be

ready to receive. If XON/XOFF control is selected or the memory switch 4-5 is set to 1, the

printer will send only 1 byte without conﬁrming the DSR signal status.

• If printing is under way, the printer will sends the then status after printing that line and

feeding the paper (the status sending timing differs from ESC u and GS I).

• Since this command is executed at deployment of the reception buffer, there may be a delay

between command reception and status sending, depending on the reception buffer

condition.

• If ASB is enabled by GS a, it is necessary to distinguish the status by this command from that

of ASB. See “6. Interface” for how to distinguish them.
