^MTa (Thermal Media)
In general, thermal printers can print on different types of media using ink ribbon (this type of
printing is called thermal transfer) or directly onto thermal paper (this is called direct thermal
printing).
The printing mode is defined with a specific machine configuration parameter or with the following
command.
In this case, a can assume two different values:
T to set the thermal transfer mode
D to set the direct thermal mode.
The instruction is ignored if the parameter is omitted or is different from these two.
^MDn (Media Darkness)
Depending on the type of medium that is going to be used, the type of ribbon used, and the printing
speed, the print quality is determined by the head temperature. There are 30 possible temperature
levels (one of which is set from the panel). By means of this command, it is possible to adjust the
head temperature (and thus print density) incrementally according to the value set during
configuration. Specifically, the parameter n is a whole number between –30 and +30
35 with the
convention of assuming all numbers without sign as being positive. After executing the current
command, the number n is added algebraically to the temperature set during configuration; the
result of the operation is the new printer temperature. Even when several ^MD commands are sent,
each one of them refers to the value set in the machine configuration. The effect of the commands is
not cumulative: it is the one resulting from the last command sent.
If the result of the command ^MD produces a temperature value over 30 or less than 0, the
temperature is assumed to be 30 and 0 respectively.
^LTn (Label Top)
In order to define the exact position of the label, this command can be used, where n is a whole
number between –64 and +64. The result is longitudinal displacement of the entire printing image
by n dots
36 in reference to the origin of the coordinates as indicated in fig. 2 on page 9. Once again,
it is assumed that numbers without sign are positive.
^JZa (Reprint After Error)
In general, after resetting following an operating error (e.g. when the paper or ribbon run out), the
printer reprints the whole label that was interrupted due to the error.
This command is used to disable this function.
The parameter a can assume one of the following two values:
Y 37 reprinting is enabled
N printing is disabled.
35
The default value is 0.

See note 5 on page 9.
37
Default value.
