To accommodate data entry, the C82303* interface board is
1
equipped with a buffer that temporarily stores data before
I
transferring it to the printer. When this buffer becomes full,
any additional transmitted data cannot be accepted
and
is
discarded.
The buffered data is transferred transparently to the printer
main board every time the printer enters the READY state. A
maximum of 512K bytes of data can be buffered with this
board depending on its setting.
