Lexmark 1200 manual Performance, Lower baud rate for the infrared connection

Infrared Menu (continued)

Menu item		Values
Window Size	Auto*
	1
		The Window Size setting specifies the maximum number of infrared frames the printer can
		receive before it must send an acknowledgment to the host computer. If Auto is selected, the
		printer automatically sets the window size during power-on 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.
Transmit Delay		Auto*
		None
		1…15
		The Transmit Delay setting defines the amount of time the printer must wait before trans-
		mitting meaningful infrared data to the host computer, as well as the amount of time the
		printer requests the host computer to wait before it transmits infrared data. If Auto is selected,
		the printer automatically sets the Transmit Delay value during power-on 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.

		The maximum baud rate possible for both the printer and the infrared adapter is automatically
		set during power-on. However, if your printer is situated in a bright or highly reflective
		environment, you may experience intermittent communication problems. If you do, select a
		lower baud rate for the infrared connection.
