GS ( H <Function 49>

[Name]

Specifies the offline response

[Format]

ASCII	GS	(	H	pL	pH	fn	m	d
Hex	1D	28	48	03	00	31	30	d
Decimal	29	40	72	3	0	49	48	d

[Range]

(pL + pH × 256) = 3

fn = 49

m = 48

d = 0 – 2, 48 – 50

[Default]

d = 0

[Description]

Specifies or turns off the offline response transmission.

d	Function
0, 48	Turns off the offline response transmission.
1, 49	Specifies the offline response transmission (not including the offline cause).
2, 50	Specifies the offline response transmission (including the offline cause).

When specifying offline response transmitting (d = 1, 2, 49, 50), offline response is transmitted when the printer goes offline for any of the following causes.

Any paper cover open
Printing stop because of paper out
Automatically recoverable error
Recoverable error
Unrecoverable error

[Notes]

Confirm that untransmitted offline responses aren't stored in the printer when specifying or turning off offline response transmitting by this function.
- When operating with a serial interface, make sure that the host PC is able to receive data before executing this function.
- When operating with a parallel interface, change the host PC to the reverse mode for confirming any responses.
Offline response is the "header to NUL" data shown below:

Send data	Hex	Decimal	Number of bytes
Header	37h	55	1 byte
Identifier	23h	35	1 byte
Offline cause (∗1)	40h – 7Fh	64 – 127	0 – 10 byte
NUL	00h	0	1 byte

Send data

Hex

Decimal

Number of bytes

Header

37h

1 byte

Identifier

23h

1 byte

Offline cause (∗1)

40h – 7Fh

64 – 127

0 – 10 byte

NUL

00h

1 byte

(∗1) When specifying (d = 1, 49), [Offline cause] is not added. Details of the offline cause differ, depending on each model.
When transmitting an offline response occurs at the same time that an untransmitted offline response is being stored, the printer transmits the latest offline response only.
You can get detailed information of offline occurrences by using the combination of ASB status and offline response with offline cause.
When specifying offline response by this function, execute response confirmation processing on the host PC for the responses from the printer.
See program example and print sample for ESC i [obsolete command] and ESC m [obsolete command] for description of response transmission process.

Bit 0 is not supported by the TM-L90 with Peeler.

When the error of bit 0 or bit 1 occurs, the error can be canceled by executing DLE ENQ (n = 2) after clearing the error cause.

When the error of bit 2 occurs, the error can be canceled by either of the following. See the printer information of GS ( E <Function 3> for memory switches details.

When memory switch [Msw8-2] is OFF: execution of DLE ENQ (n = 2) or opening/closing the cover

When memory switch [Msw8-2] is ON: execution of DLE ENQ (n = 2)

When memory switch [Msw8-1] is OFF: execution of DLE ENQ (n = 2) or pressing the paper feed button [TM-L90 with Peeler]

When memory switch [Msw8-1] is ON: execution of DLE ENQ (n = 2) [TM-L90 with Peeler]

Bit	Binary	Hex	Decimal	Function
0	0	00	0	Roll paper cover open error hasn't occurred. (When Msw [8-8] is OFF)
