Details
Click the Details tab to see the following options:
Set the Timeout settings.
Not Selected: Type a value of 0, or between 15 and 999, in this text
box to change the number of seconds Windows waits before
notifying you that a printer is off-line. The default is 15 seconds.
Transmission Retry: On large or multiple-page documents you
may see an Alert message that the printer is no longer accepting
data before the job is completely sent to the printer. When using a
shared printer, you should set this option to a larger value, such as
850 to avoid these unnecessary timeouts. Type a value between 45
and 850 in this text box; the default setting is 45 seconds.
