35. ESC _
Restore factory defaults and save them to nonvolatile RAM
[Code] [1Bh] + [5Fh]
[Outline] Select font A, no bold, no underline, etc. Restore tab defaults.
The parameters are read from the flash memory.
Downloaded font and downloaded bit image are cleared.
Copy internal fonts A and B to user fonts. DIP switches are read again.
Data in the input buffer is not cleared.

36. ESC ‘
Transmits the current power supply voltage and the print head tempera-
ture.
[Code] <1B>H<60>H
[Outline] The printer transmits two bytes data. First byte is the power
supply voltage given as 0.1 mV plus 20h. the second byte is
the print head temperature, in degrees Celsius, plus 20h.
[Example] If the battery voltage is 6.4 V, and the print head temperature
is 33°C, the printer will transmit <60h><41h>, which is
<40h+20h><21h+20h> or <64+32><33+32>.
37. ESC a n
Aligning the characters
[Code] [1Bh] + [61h] + n
[Range] {0 <= n <= 2}
{4 <= n <=6 }
[Outline] This command is extended and has the following format:
All the printed text data, the barcode or the raster bit image (GS v0)
within one line are aligned in the specified position. If used before
printing a barcode with this command can be specified vertical
direction for printing the barcode.
34. ESC \ n1 n2
Specifying the Relative Positions
[Code] [1Bh] + [5Ch] + n1 + n2
[Range] {0 <= n1 <= FFh}
{0 <= n2 <= FFh}
[Outline] The printing start position is specified in the number of
dots(1/203 inch unit) from the current position.
• Rightward direction is taken as plus and leftward direction as minus.
• To specify N dot in minus (left) direction, use a complement of N for
assignment.
– N dots = 65536 – N
• The number of dots is divided by 256, whose quotient is taken as n2
and the residual as n1.
• There are 384 dots per line (positions from 0 to 383).
[Caution]
• Specifying exceeding the beginning of the line or the end of the line
ignored.
[Default]
• The initial value is not specified.
