Help system

What’s this help

Windows 95 and NT 4.0 What’s this? help is supported. To use What's this? Help:

• Click the right mouse button on a control to display a context-sensitive menu,

then select What’s this? to display a popup help window.

• Click the ? button located on the top-right corner of the frame next to the close

(x) button to change the cursor to an arrow with a question mark. Selecting a

control with this special cursor displays the popup help window for that feature.

• Press the F1 key to display the help window for the control that currently has

focus.

Page-sensitive help

Press the common Help button to open the driver help system to the contents that

correspond to the active property page. There is also a Help button with dialog-sensitive

help for the Custom Paper Size, Watermarks Details, Print Quality Details, and Job

Retention Options dialog boxes.

Constraint messages

Constraint messages are any unsolicited messages that appear in response to specific

actions you take. These messages alert you to selections that are illogical or impossible

given the capabilities of the printer or the current settings of other controls. For example,

if you select duplex printing and then changes the paper type to transparencies, a

message appears asking you to resolve this conflict. (See below for a table of the

constraint messages.) Figure 40 shows a typical constraint message.

Figure 40: A typical constraint message with an OK button

Whenever a constraint message appears with an OK and a Cancel button, the

interpretation of the buttons is as follows:

• Selecting OK accepts the change that was just made, and the driver then resets the

conflicting control to a setting that is compatible with the new value.

• Selecting Cancel rejects the change that was just made, setting the control back to

its previous value.
