Receipt Throughput:
Maximum throughput is achieved at any dot coverage up to 25%,
which includes any amount of text. But above that, throughput is
dependent on the dot coverage and available electrical power.

Note: Standard receipt has approximately 12% dot coverage.
A full line of text is approximately 25% dot coverage.
Graphics are approximately 40% dot coverage.
Barcodes have approximately 50% dot coverage.
A solid black line is 100% dot coverage.
In order for an application to achieve the fastest throughput it must
ensure that data arrives at the printer at least as fast as it is printed, so
the printer will be able to print each line after the preceding line,
without stopping to wait for more data. Ideally, an application will
send all the data for an entire customer receipt without pausing
between characters or lines transmitted.
