Check your printer manual.
There appears to be a printer error. If the printer is still not online and
does not show an error message on the control panel display, please refer
to your printer manual for further information on how to correct the
error, or for information on how to contact Hewlett-Packard technical
support if you can't correct the error. (Note that your printer manual may
be either printed on paper or stored electronically on a CD-ROM.)
After you have resolved the printer error, if you still have problems
connecting the printer to the network you can restart this troubleshooting
utility. Click on the button below to return to the beginning of
