43) Firmware download
:<<GS
：
>>
Code
: <1D>h + <3A>h
Description : Download printer firmware in hexadecimal code and rewrite firmware
according to the outcome.
* Dn is firmware’s hex code that complies with INTELLEX Hex format.
44) Reverse print set and reset :<< GS B n >>
Code
: < 1D > h + < 42 > h + n
* < 00
≤
n
≤
FF >h
Function
: Sets and resets reverse print.
* “n” is available only for the least significant bit.
* The least significant bit controls as follows:
n0 Function
0
Resets black-white printing
1
Sets black-white printing
* The characters incorporated and downloaded can be reverse printed.
* The right side space of character set by [Set right space of a character] is also
included for reverse print. However, it does not cover the skipped space made by
bit image, download bit image, NV bit image, barcode, HRI characters, horizontal
tab, specify absolute position, specify relative position.
* It does not include the space between the lines.
* Reverse print has a priority over “underline specified”. If a character is reversed,
the character is not underlined. However, the underline setting remains effective.
* If “highlight” or “double strike” is set on the reverse print, the print may result in
damages.
* The default value of “n” is [00]h.
45) Back feed
:<< ESC B n >>
Code
: < 1B > h + < 42 > h + n
* < 00
≤
n
≤
FF >h
Description
: Feeds the paper backward.
* Paper feed amount is specified by n dot line.
* Paper is not fed backward when [00]h is set.
* If this command is entered consecutively, paper may be jammed. To avoid this
problem, enter only once and feed paper in the forward direction.
* Double strike print is available by using this command.
* Considering the backlash, there may be a gap of printing.
* When data remains in the print line buffer, it first prints data, then back feeds.
46) Software reset
:<< DC1 >>
Code
: < 11 > h
Description
: Restart the firmware as the same procedure as power on.
* This command is stored in the receive input buffer and activated in sequence.
