The LK-Px series supports the following commands for printing characters and advancing paper.
HT
[Name] Horizontal tab
[Format] ASCII HT Hex 09 Decimal 9
[Description] Moves the print position to the next tab position.
[Details] ·This command is ignored unless the next tab position has been set.
·If the next horizontal tab position exceeds the printing area, the printer sets the printing position to [Printing area width + 1].
·Horizontal tab positions are set using “ESC D”.
·If this command is received when the printing position is at [printing area width +1], the printer executes print buffer-full printing of the current line and horizontal tab processing from the beginning of the next line.
·The default setting of the horizontal tab position for the paper roll is font A (12 x 24) every 8th character (9th, 17th, 25th, … column).

or there is an error status.
·When Auto Status Back (ASB) is enabled using the GS a command, the status transmitted by the DLE EOT command and the ASB status must be differentiated.
Example : In ESC *
m nL nH d1…dk
d1=<10>H, d2=<04>H, d3=<01>H
·This command should not be used within the data sequence of another command that consists of 2 or more bytes.
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 then DLE EOT 3 interrupts before n is
received, the code <10> H for DLE EOT 3 is processed as the code for ESC 3 <10>H.

the NV bit image you are defining.
·yL, yH specifies (yL + yH × 256) × 8 dots in the vertical direction for the NV
bit image you are defining.
·This command cancels all NV bit image that have already been defined by this command.
The printer can not redefine only one of several data definitions previously defined.
In this case, all data needs to be sent again.
·From the beginning of the processing of this command till the finish of
hardware reset, mechanical operations (including initializing the position
of the printer head when the cover is open, paper feeding by using the
FEED button, etc.) cannot be performed.
·During processing this command, the printer is in BUSY when writing the
data to the NV user memory and stops receiving data. Therefore it is
prohibited to transmit the data including the real-time commands during
the execution of this command.
·NV bit image means a bit image which is defined in a non-volatile memory
by FS q and printed by FS p.
·In standard mode, this command is effective only when processed at the
beginning of the line.
·In page mode, this command is not effective.
·This command is effective when 7 bytes <FS-yH> is processed as a normal value.
·When the amount of the data exceeds the capacity left in the range
defined by xL, xH, yL, yH, the printer processes xL, xH, yL, yH out of the defined range.
·In the first group of NV bit image, when any of the parameters xL, xH, yL,
yH, is out of the definition range, the command is disabled.
·In groups of NV bit image other than the first one, when the printer
processes xL, xH yL, yH out of the defined range, it stops processing this
command and stars writing into the NV images. At this time, NV bit image
that haven’t been defined are disabled (undefined), but any NV bit
images before that are enabled.
·The d indicates the definition data. In data (d) a 1 bit specifies a dot to be
printed and a 0 bit specifies a dot not to be printed.
·This command defines n as the number of a NV image. Number rise in
order from NV bit image 01H. Therefore, the first data group [xL xH yL yH
30
Page 31
d1...dk] is NV bit image 01H, and the last data group [xL xH yL yH
d1...dk] is NV bit image n. The total agrees with the number of NV bit
images specified by command FS p.
·A definition data of a NV bit image consists of [xL xH vL vH d1...dk].
Therefore, when only one NV bit image is defined n=1, the printer
processes a data group [xL xH yL yH d1...dk] once. The printer uses
([data:(xL + xH ×256) × (yL + yH × 256) × 8] + [header:4]) bytes of NV memory.
·The definition area in this printer is a maximum of 2M bits (256K bytes).
This command can define several NV bit image, but cannot define a bit
image data whose total capacity [bit image data + header] exceeds 2M bytes (256K bytes).
·The printer is busy immediately before writing into NV memory, regardless
of the setting of DIP switch 2-1.
·The printer does not transmit ASB status and perform status detection
during processing of the command even when ASB is specified.
·When this command is received during macro definition, the printer ends
macro definition, and begins performing this command.
·Once a NV bit image is defined, it not erased by performing ESC @, reset, and power off.
·This command performs only definition of a NV bit image and does not
perform printing. Printing of the NV bit image is performed by the FS q command.
[Notes] ·Frequent write command execution may cause damage the NV memory.
Therefore, it is recommended to write the NV memory 10 times or less a day.
·The printer performs a hardware reset after the procedure to place the
image into the NV memory. Therefore, user-defined characters,
downloaded bit image, and macros should be defined only after
completing this command. The printer clears the receive and print buffers
and resets the mode to the mode that was in effect at power on. At this time,
DIP switch setting are checked again. n is the number of the NV bit
