Setting the Memory Switches
With the “memory switch (customized value,” which is a software switch of this printer, you can
set:
•Print density
•Print speed
•Number of head energizing parts
•Single-color printing/two-color printing
• Black-color density in two-color printing
Use the Memory Switch Setting Utility or a command to set the memory switches.
Selecting the print density
Selectable from levels 1 to 13 (light ∼ dark).
Selecting the print speed
Selectable from levels 1 to 9 (low ∼ high). (Initial setting: level 9)
In power saving mode, all customized value settings are ignored.
• For detailed information about the memory switch utility, see the user’s manual for the
Memory Switch Setting Utility.
• For detailed information about ESC/POS commands, see the ESC/POS Application
Programing Guide.
The print density can be set with DIP switches (2-3/2-4) or the customized value. (See
"Setting the Memory Switches" on page 43.) The initial setting of the customized value is
“Depends on the DIP switch settings.” If the customized value is changed, the value set
with the customized value is enabled.
Depending on print conditions such as print duty, print head temperature, or data
transmission speed, print speed is automatically adjusted which may cause white lines due
to intermittent print (the motor sometimes stops). To avoid this, keep the print speed
constant by setting it lower, or set the transmission speed higher in case of the serial
interface. (See "Transmission speed (DIP switch 1-7/1-8)" on page 36.)
