3.4.5Resetting 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.

3.4.6Memory

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.

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.
