Answer. On HP printers, a “cold reset” causes the printer to return to its factory default settings, which among other things, causes it to try and retrieve its configuration information from a BOOTP server.
Select Start > Settings . Go to Devices > Printers & scanners > select a printer > Manage. Then select Set as default.
The printer drops the network connection, resets its network settings to their factory defaults, and prints a Printer Configuration label and a Network Configuration label.
Restart your printer by turning it off, waiting 10 seconds, and disconnecting the power cord from your printer. Then, turn off your computer. Connect the printer power cord to the printer and turn the printer back on.
On the sign-in screen, press and hold the shift key, click the power icon , select Restart, and continue pressing the shift key until the Choose an option screen displays. Click Troubleshoot. Click Reset this PC, and then click Remove everything.
One of the easiest ways to reset your PC without a password is by issuing the Restart command while pressing the SHIFT key. This allows us to invoke the same Reset operation as from the Windows Repair menu. On the Choose an option screen, click Troubleshoot: Reset your PC or see advanced options. Choose Reset this PC.
Restart your computer, and then immediately press the F11 key repeatedly. Click Start . Press and hold the Shift key, click Power, and then select Restart while holding the Shift key. Continue holding the Shift key while the computer restarts.
Turn on your computer and press the F11 key immediately and repeatedly. Release the key until you see the Choose an option window. Select Troubleshoot and then click Reset this PC.
Turn the printer off then back on. If the issue persists, turn the printer off, unplug the power cord and then wait at least three minutes before plugging the power cord back in and turning the printer back on. If the issue persists, ensure the product is running the latest firmware available from HP.com.

Even though the 1600 is a different printer, I followed the above: “…go to “System Configuration”; then to “Print Quality”; I then get a choice of “Replace Supplies” and then “Overide Out”…” Selecting “Overide Out” got my 1600 back to printing, although I did have do perform the steps TWICE before it seemed to take affect.
