Memory switch setting can be changed by a command or by manual operation.
a)Change by command
Memory switch can be changed by a command. For details, refer to “8. Print Control Function”.
When the printer receives the command, it outputs a BUSY signal and enters memory setting mode. After writing into memory switch, software resetting is carried out and the receive buffer/print buffer are cleared causing each set value to return to the initial value and then the contents of the memory switch(es) are reloaded.
Commands are set one by one. Use care when changing two or more set values.
