3.4.5 Resetting the Printer While Printing
When the data with a lot of dots is printed, the print data may be missing and then, the printing may
often continue in the state that each setting by the commands is reset.
This is because too many print dots decrease the voltage, which results in the activation of the reset
circuit of the printer.
The commands which tend to increase the number of print dots are:
• Underline
• Reverse
• Ruled line (in case that the number of dots is many)
• Bitimage
Case that a horizontal line is printed when printing a full line of “H” characters without spaces
between the characters.
The print density set command (case that the print density is set at over 100%) expands the length
of strobe, which very often resets the settings, although this command does not increase the
number of print dots. Be aware of these points when using the printer.
3.4.6 Memory
1. Input buffer memory
An input buffer memory (RAM) with the capacity of 4,096 bytes is built in the printer.
2. User memory
A user memory (RAM) with the capacity of 16,384 can be used when setting the printer in Mode 3.
The data registered in this memory are cleared when turning off the power.
This memory is used when using the downloaded characters, the user-defined characters, and
the downloaded Bitimages.
The memory used by the downloaded characters and user-defined character is restricted as
follows. The remaining is used for the downloaded Bitimages. However, it can release the
memory of the downloaded character and use-defined character so that ensuring the capacity
for Downloaded Bitimage.
The memory capacity immediately after the initialization
Application Capacity (in byte)
Downloaded character 4,560
User-defined character 1,080
Downloaded Bitimage 10,744
Total 16,384
The capacity for the downloaded characters and the user-defined characters is readily ensured
at the initialization.
This area can be released by a command to use the area for the downloaded Bitimages.
When registering the downloaded Bitimages, calculate the remaining capacity of the memory
before registering them.
Be sure that the data with the larger capacity than the remaining capacity is ignored even if you
trying to register such data.
