use the attached handset (hp officejet 4250 series only)
You can use the attached handset to answer incoming calls, make phone calls,
receive faxes, and send faxes. While the HP Officejet is processing another job,
such as copying, scanning, or printing, you can still use the handset for phone
calls.
Note:
If the HP Officejet is sending or receiving fax data, you will not be
able to use the handset for phone calls. If you pick up the handset during
faxing, you will not hear a dial tone. Wait for the HP Officejet to finish
sending or receiving the fax before using the handset.
Use this section only if you have the HP Officejet 4250 Series (with the attached
handset).
