Real-time request to printer
ASCII DLE ENQ n
Hex 10 05
Decimal 16 5
n = 0, n = 2
The printer responds to a request from the host specified by n.
n = 0: Recovers to on-line state.
n = 2: Recovers from an error after clearing the receive and print
buffers.
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
Set right-side character spacing
ASCII ESC SP n
Hex 1B 20 n
Decimal 27 32 n
0 ≤n ≤255
Sets the character spacing for the right side of the character to [ n
×0.122 mm {1/208 inches}] .
The right-side character spacing for double-width mode is twice the
normal value.
