This document explains how to print the built-in (internal) tests of the HP Deskjet 450 printer. These tests can be used to ensure the printer is working properly or to troubleshoot specific printer issues.
If it is necessary to call the Customer Care Center, a Diagnostic page and a Configuration page should be printed to obtain printer information. Such information is useful to the Customer Care Center in helping to troubleshoot printer problems. Printer information is also available from the Toolbox by clicking Printer Hardware under the Information tab. Information on the printer, battery, connectivity, and media types used is available.
