Loading character generators
Indicate "Ready to load character generator"
Function:
Description:
This command is used to inform the printer that a new character generator
should be loaded. All activities in the printer will be stopped, and all data will be
deleted. Then the host is informed that the printer is ready to load. The number
of bytes to be loaded is also indicated. The following formula is used to calculate
the number of bytes to be loaded:
Number = n1 +256*n2 +65536*n3.
Parameter ’d’ target
The passbook and document printer with the model variants ’Medium’ or
’Comfort’ accommodate additional character generators in the extension
memory. Thus it is possible to load a second PC table or fonts for the Asian
regions up to a maximum size of 2 MB.
’Ready to load’ is indicated by sending the sequence ESC F N T to the host.
