2. Command format
[Name] The name of the command.
[Format] The code sequence.
ASCII indicates the ASCII equivalents.
Hex indicates the hexadecimal equivalents.
Decimal indicates the decimal equivalents.
[ ]k indicates the contents of the [ ] should be repeated k times.
[Range] Gives the allowable ranges, if any, for the command parameters.
[Description] Describes the function of the command.
[Notes] Provides important information on setting and using the printer command, if
necessary.
[Default] Gives the default values, if any, for the arguments.
[Reference] Gives the references, if any.
[Example] Provides examples for using the command.
3. Explanation of terms
Receive Buffer
The receive buffer is used to store data from the Host. All received data is stored in this buffer
temporarily and processed in the order received.
Print line buffer
Print line buffer is used to store one line of the data which will be sent to printer.
Print line buffer is full
It means current line buffer space is not enough to contain the current processing data.
Print line buffer empty

the line).
The beginning of one line
The pointer is at the beginning of the printing line. It will not meet such requirement if the print
line buffer was not empty or the command had set the print position.

REGO Thermal Printer Technical Manual

Effective printing width
It refers to the maximum printing width of the printer which depends on the printer itself. For
example: for a 80mm paper width printer, its printing width is 72mm(576 dots), but for a 58mm
paper width printer, the printing width can be 48mm(384 dots).
Printing area
The printing area can be set by command. Printing area must be smaller or equal to effective
printing width.
Ignore
In this state, all the codes including parameters are invalid, without any action.
Black mark mode
Black mark is a black block which is pre-printed on the paper and through it you can achieve
positioning. The printer can be set to Black Mark mode, in this situation, if you sent the command
FF or press the feed button, the printer will reach a black mark position. Please check FF
command to get detailed process of positioning, and check the specifications of black mark in
Appendix B.

[Description] Define user-defined characters.
y specifies the number of bytes in the vertical direction.
c1 specifies the beginning character code for the definition, and c2 specifies the final code.
x specifies the number of dots in the horizontal direction.
[Notes] 
The allowable character code range is from ASCII code <20>H to <7E>H (95 characters).
It is possible to define multiple characters for consecutive character codes.
If only one character is desired, use c1 = c2.
d is the dot data for the characters. The dot pattern is in the horizontal direction from the left
side. Any remaining dots on the right side are blank.
The data to define a user-defined character is (y× x) bytes.
Set a corresponding bit to 1 to print a dot or 0 to not print a dot.
The user-defined character definition is cleared when:
-ESC @ is executed.
-ESC ? is executed.
-FS q is executed.
- GS * is executed.
-2-D bar code is executed.
-The printer is reset or the power is turned off.
When the user-defined characters are defined in font B (9 × 17), only the most significant bit of
the 3rd byte of data in vertical direction is effective.
[Default] The internal character set

[Notes] 
The printer can underline all characters (including right-side character spacing),but cannot
underline the space set by HT.
The printer cannot underline 90° clockwise rotated characters and white/black inverted
characters.
When underline mode id turned off by setting the value of n to 0 or 48, the following data is not
underlined, and the underline thickness set before the mode is turned off does not change. The
