Product Description

1.2.6 Preventing Data Transfer Time-Outs

Generally, hosts abandon data transfer to peripherals when a peripheral is in
the busy state for dozens of seconds continuously. To prevent hosts from
entering this kind of time-out period, the printer slows down the data
reception rate to about one byte per second when there is less than 4kb of
free space in the printer buffer. Data reception comes to a complete stop if the
free space is less than 32 bytes, but returns to one byte per second when free
space reaches 1KB or more.
