The Window Size setting specifies the maximum number of
infrared frames the printer can receive before sending an
acknowledgment to the host computer.
Select Auto to automatically set the window size during a power
on reset to maximize link performance.
In most cases, Auto is the recommended setting. If you have
trouble printing using the infrared port, changing the Window
Size setting to 1 may resolve the problem.

The Transmit Delay setting defines the amount of time in
seconds the printer must wait before transmitting meaningful
infrared data to the host computer, as well as the amount of
time the printer requests the host computer to wait before trans-
mitting infrared data.
Select Auto to let the printer automatically set the Transmit
Delay value during a power on reset to maximize link
performance.
In most cases, Auto is the recommended setting. If you have
trouble printing using the infrared port, selecting a high Transmit
Delay setting, such as 15, may resolve the problem.
