The printer parameter settings are subject to the last settings. The printer
parameters can be set via the menu of printer operation interface, user
software (including drivers and the third-party software), printer commands,
etc. For example, the printer menu and the printer drivers in computer can
be used to set the print speed. Although the print speed has been set via
the printer menu, it will be updated to the speed set by the driver in the
computer after using the printer driver in computer to print.
3.1 Print head pressure and pressure position
The print head pressure adjustment device is equipped with two
print head pressure adjustment knobs (8), and each knob can adjust
the print head pressure steplessly. Turn the knob leftward, the print
head pressure will increase (see Fig.3.1.1). The pressure position
lock knob (9) can adjust the pressure position and lock the pressure
- 13 -
Fig. 3.1.1
The pressure needs to be adjusted under the following conditions:
1) When the print head pressure cannot meet the requirement (e.g.
the ribbon cannot be rewound smoothly), turn the print head
pressure adjustment knob to increase the pressure;
2) Different pressure size and pressure position can be selected
when use label paper with different widths for printing. The two
print head modules are symmetrical with the print contents.
3) If the print quality does not meet the requirements when adopts
thicker media, the print head pressure can be increased
Set the print head pressure to a lower level as long as the print quality is
If ribbon crack occurs when print at a low temperature environment, the
operation of increasing the print head pressure is the priority measure, and
the operation of reducing the print darkness or print speed can also be
taken when meet the use requirements.
