3–35 Configuring the Printer
Paper Instruction Pol
Values: Standard or Inverted.
It must be set to match the host computer.
PI Line is used to enable or disable paper motion.
Strobe Filter
Values: Enable or Disable.
It must be set to match the host computer.
When set to the short filtering mode, this filter will reject all NSTROBE pulses
of less than 63 ns. When set to the default long filtering mode, all strobes of less
than 313 ns will be rejected.
Fast Busy
Values: Enable or Disable.
It must be set to match the host computer.
In fast busy mode (default), busy will be driven high when the data has been
successfully clocked into the printer. In slow busy mode, busy will be asserted
only if needed to delay the interface for some reason. In this mode, the host must
wait for the NACK pulse before sending the next word of data. The use of slow
busy mode is not recommended.
Trailing Edge
Values: Enable or Disable.
It must be set to match the host computer.
Normally, data is sampled from the data lines [8–1] on the falling edge of the
filtered NSTROBE signal. This option allows the data to be sampled on the
rising, or trailing, edge.
