Help system

The HP PCL 6 printer driver includes a full-featured Help system to provide assistance with printing
and configuration options.
"What's this?" Help
Windows XP, Windows Server 2003, Windows Server 2008 and 2008 R2, Windows Vista, and
Windows 7 support What's this? Help. You can gain access to What's this? Help messages in any of
the following ways:
●
Right-click a feature or control. A pop-up Help window appears.
●
Click the ? button in the upper-right corner of the frame, next to the X, to change the cursor to an
arrow with a question mark. When you use this special cursor to select a control, the pop-up
Help window for that feature appears.
●
Click a feature or control, and then press the
control appears.
Incompatible print settings messages
Incompatible print settings (constraint) messages are unsolicited messages that appear in response
to specific print-driver selections. These messages alert you to selections that are illogical or
impossible given the product capabilities or the current settings of other controls.
NOTE: Constraint messages are limited, and the underlying software architecture might accept
some settings that are illogical or impossible for the product to perform. Sending a job with
incompatible settings can lead to unexpected results. If print jobs do not print as expected, check the
product documentation for the product capabilities.
In supported Windows operating environments, some technically invalid print-driver configurations
result in warning messages. For example, duplexing is not possible when printing an envelope. The
following figure shows an incompatible print settings warning.
