HP Color LaserJet CP2020 Series - Software Technical Reference

Help system
The HP PCL 6 print driver and HP PS Universal Print Driver include a full-featured Help system to provide
assistance with printing and configuration options. The following Help options are available.
●
“What's this?” Help
●
Constraint messages
“What's this?” Help
"What's this?" Help is supported in Microsoft Windows 2000 and Windows XP. Access the "What's this?"
Help messages in any of the following ways:
●
Right-click a control button on a screen. For example, on the Properties tab screen, right-click
either the Printing Preferences control or the Print Test Page control. A small What's this? box
appears. Right-click on the What's this? box and a pop-up Help window appears.
●
Click the ? button in the upper-right corner of the screen frame, next to the X, to change the cursor
to an arrow with a question mark. Use this special cursor to select a control, and the pop-up Help
window for that feature appears.
●
Press the F1 key, and the Help window for the currently selected control appears.
Constraint messages
Constraint messages are unsolicited messages that appear in response to specific actions that are
illogical or impossible given the capabilities of the product or the current settings of other controls. For
example, if you click Print on Both Sides and then change the paper type to Transparency, a message
appears with options on how to resolve this conflict.
Figure 4-1 A typical constraint message
Whenever a constraint message appears with Restore my previous settings or Keep this setting,
and I will change it later buttons, the action of the buttons is as follows:
●
To reject the change that was just made, returning the control to its previous value, click Restore
my previous settings and then click OK.
●
To accept the change that was just made, click Keep this setting, and I will change is later and
then click OK. This brings back the driver settings where the user can resolve the conflict.
