(2) Capacity of memory size
Allocated memory size depend on used function. User-defined character and downloaded character is
allocated size of 9784 and 6248 bytes respectively. Optional fonts, routine function or stamp is allocated
size of (number of data + Memory control Information). Moreover, registration of routine function and
stamp requires the above-mentioned size per registration data.
(3) Precautions for stamp function
Do not use the commands such as which to be allocated or freed as listed below during stamp operation.
Table 6-4 Commands for Allocating or Freeing Memory Area
Command Command name
DC2 'T' Stamp Define
DC2 'U' Stamp Clear
DC2 'P' Define optional font
DC2 'Q' Erase optional font
DC2 'E' 0 Set routine format
DC2 'E' 1 Set routine parameter data
DC2 'E' 3 Delete all routine data
DC2 'z' 0 Page Mode Select
DC2 'D' Downloaded characters area operation
DC2 'G' User-defined character area operation
DC2 'R' User Area Initialization
If the commands listed in Table 6-4 are input during selection of the stamp, the stamp selection is
canceled.
(4) Initialization of memory
The printer does not erase the content of the memory using the AC adapter or the battery pack with active
voltage even if Reset command or Power off command is input or the printer is turned the power off.
However, the printer initializes the memory during its next start-up when disconnecting the power supply
or executing the User Area Initialization command.
(5) Memory usage at two-dimensional bar code function
At two-dimensional bar code print, empty area of the external RAM is used temporarily at bar code print.
The two-dimensional bar code printing performs depending on their parameter, available memory
capacity and settable data size as described below:

When the parameter of the command is outside the range:
CPU ignores the part outside and processes the remaining data as normal codes.

When the available memory capacity is short:
All of data is processed as normal code.

When the command is normal and memory area has been allocated but the data more than
maximum data size is specified:
All of the data is discarded. Since settable data size varies depending on the type of
two-dimensional bar codes, refer to each explanation of two-dimensional bar code commands.
Moreover, note that settable data size changes in accordance with the value of specified parameter.
