to check:

printer’s front-panel menu selections).

Refer to the User’s Guide for further information on how to configure the
system with correct settings.
Media
Always make sure that the customer is using the appropriate media for the
required image and that it is consistent with the software application being
used. To ensure color accuracy and print quality performance of the printer,
only media types that have been certified for the printer should be used.
Use of non-HP media or HP media not certified for the printer may
significantly reduce the color and print quality of the required images. For
details of HP media, refer to the User’s Guide or the Media Guide for the
HP DesignJet CP Printers.
To have accurate colors, the media settings must match the type of
media loaded in the printer.
If the customer is using non-HP media with HP drivers, the colors in
the required print may not be accurate. Advise the customer to use
HP media if they want to improve the accuracy of the colors.
