n = 3 : Error status
Bit Off/On Hex Decimal Function
0 Off 00 0 Not used. Fixed to Off.
1 On 02 2 Not used. Fixed to On.
Off 00 0 No mechanical error. 2
On 04 4 Mechanical error occurred.
Off 00 0 No auto-cutter error.
3
On 08 8 Auto-cutter error occurs.
4 On 10 16 Not used. Fixed to On.
Off 00 0 No unrecoverable error. 5
On 20 32 Unrecoverable error occurs.
Off 00 0 Automatic recover error. 6
On 40 64 No automatic recover error.
7 Off 00 0 Not used. Fixed to Off.
Bit 2 : If these errors occur due to paper jams or the like, it is possible to
recover by correcting the cause of the error and executing DLE ENQ 2.
If an error due to a circuit failure (e.g. wire break) occurs, it is
impossible to recover.
n = 4 : Continuous paper sensor status
Bit Off/On Hex Decimal Function

1 On 02 2 Not used. Fixed to On.
Off 00 0 Paper near-end sensor. Paper adequate.
2, 3
On 0C 12
Paper near-end is detected by the paper near-end
sensor.
4 On 10 16 Not used. Fixed to On.
Off 00 0 Paper end sensor. Paper adequate. 5, 6
On 60 96 Paper end is detected by the paper end sensor.

DLE ENQ n
[Name] Real-time request to printer
[Format] ASCII DLE ENQ n
Hex 10 05 n
Decimal 16 5 n
[Range] n = 2
[Description] The printer responds to a request from the host specified
by n.
n = 2: Recovers from an error after clearing the receive
and print buffers.
[Notes]
• This command should not be used within the data sequence of another
command that consists of two or more bytes. For example,
If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the
host computer) goes to MARK before n is transmitted, and DLE ENQ 2
interrupts before n is received, the code <10>H for DLE ENQ 2 is
processed as the code for ESC 3 <10>H.
• This command n = 2 is valid only when a mechanical error or an auto-
cutter error has occurred.
• DLE ENQ 2 enables the printer to recover from an error after clearing
the data in the receive buffer and the print buffer.
The printer retains the settings (by ESC !, ESC 3, etc.) in effect when the
error occurred. The printer can be initialized completely by using this
command and ESC @. This command is enabled only for errors that have
the possibility of recovery
ESC SP n
[Name] Set right-side character spacing
[Format] ASCII ESC SP n
Hex 1B 20 n
Decimal 27 32 n
[Range] 0 ≤ n ≤ 255
[Description] Sets the character spacing for the right side of the
character to [ n x 0.122 mm {1/208 inches}] .
[Notes] The right-side character spacing for double-width mode is
twice the normal value.
[Default] n = 0
