Chapter 1 Product Overview
NV Memory (Non-Volatile Memory)
The printer's NV memory stores data even after the printer power is turned off. NV memory contains the
following memory areas for the user:
• NV graphics memory
• User NV memory
• Memory switches
• R/E (Receipt Enhancement)
•User-defined page
• Maintenance counter
As a guide, NV memory rewriting should be used 10 times or less a day when you program
applications.
NV Graphics Memory
1
Graphics, such as shop logos to be printed on receipts, can be registered. Even with a serial interface model
whose communication speed is low, high speed graphic printing is possible.
TM-T20II Utility or ESC/POS commands can be used for the graphic registration.
TM-T20II Utility or NV Graphics Information Print Mode can be used for the confirmation.
User NV Memory
You can store and read text data for multiple purposes, such as for storing a note including customizing or
maintenance information of the printer.
Use ESC/POS commands to store and read the text data.
Memory Switches
With the memory switches, which are software switches for the printer, you can configure various settings
of the printer. For information about the memory switch, see
Enhancement" on page 47.
"Setting the Memory Switches/Receipt
19
R/E (Receipt Enhancement)
Registered graphics in the NV Graphics Memory can be printed automatically, as a top logo before receipt
printing or as a bottom logo before cutting paper.
TM-T20II Utility or ESC/POS commands can be used for the settings.
TM-T20II Utility or Receipt Enhancement Information Print Mode can be used for the confirmation.
User-defined Page
You can store character data in the user-defined page (character code table: page 255) so that you can also
print characters not resident in the printer.
For the character code table, see "Character Code Tables" on page 101.
Maintenance Counter
With this function, printer information, such as the number of lines printed, the number of autocuts, and
printer operation time after the printer starts working, is automatically stored in NV memory. You can read
the information with the Status API of the APD, OPOS ADK, or ESC/POS commands to use it for
periodical checks or part replacement.
• You can also check the head running length and number of times of autocutting with the self-
test (see
• The maintenance counter value is normally saved in the NV memory every 2 minutes
(maximum of 4 minutes). However, it is not automatically saved when the product is in the
power-saving mode or when the power is turned off without using the power switch.

make the paper width setting with the memory switch. For information about how to change
the paper width, see
• The printing speed changes automatically depending on the applied voltage and head
temperature.
• The maximum printing speed may not be achieved depending on the type of interface, the
setting of data transmission speed, and the combination of control commands.
• If the data transmission speed is slower than the maximum printing speed, the printing speed
may fluctuate and the print result may become shaded and/or dot displacement in paper
feeding may occur. Furthermore, if the data transmission speed is much slower than the
maximum printing speed, intermittent printing will occur.
• There might be a blank feed of a 10-dot line at the maximum before printing because printing
of ladder bar codes and 2-D symbols only starts after reaching the specified speed.

• Paper must not be pasted to the roll paper core.
• Use of thermal paper with a pre-printed recording surface should be avoided. Using it can
cause the thermal head to stick to the thermal paper surface during printing, and cause
printing failure and other problems. The pre-printing also can result in reduced print density.
Using thermal paper with a pre-printed recording surface, pre-printing should be done in
accordance with the conditions (ink type, printing and other conditions) recommended by the
paper manufacturer, and the thermal paper should be checked to ensure that there is no
faulty printing, loss of print density, or other problems.

The maximum printable area of paper with a width of 79.5 ± 0.5 mm is 72.0 ± 0.2 mm (576 dots) and the
approximate space is 3.0 mm on the left side on the left side and 4.5 mm on the right side.

• The values above may vary slightly as a result of paper slack or variations in the paper. Take
this into account when setting the cutting position of the autocutter.
• When removing cut paper, the remaining roll paper is pulled at the uncut section and the
pitch of the next print may be reduced. When printing after cutting paper for prints with no
pitch reduction, feed the paper about 1 mm {16/406 inches} before printing.
• When leaving paper loaded for an extended period of time, make sure you feed about 40 mm
of paper. This can prevent paper from wrinkling and causing prints to be too light.

Electrical Characteristics
Print ratio 80% 100%
Print example
Print length 30 mm {1.18"} 20 mm {0.79"}
58 mm {2.28"}
72 mm {2.83"}
Operating voltage DC 24V ± 7%
Current consumption
(24V, 25°C, standard print
density)
If printing is continuously performed with a high ratio, the overcurrent protection may be
activated and result in uneven print density or a low voltage error. Therefore, the printing length
must not exceed the following values when printing with high print ratio.
Print ratio: Number of dots being energized per one dot line/Total number of dots per one dot
Standby Mean: Approximately 0.1 A
Operating Mean: 1.8 A (M267A), 1.5 A (M267D, M267E)
Note: When print ratio is approximately 18%
• Continuous printing for 50 lines (repeating 20H-7FH)
* Font A, 48 columns, ASCII character
• 5 line feeding
