Toshiba Satellite, hp photosmart B110, HPLIP 3.12.10

Following an earlier thread, I've installed the latest version of hplip, and am having problems getting through the last stages of adding the printer.
The HP Device Manager-Setup (page 1 of 3)shows USB, Network, or Wireless(with temp usb cable)
Choosing the last, clicking on Next opens another window - Device Manager - Wifi Configuration (page 2 of 5), where my printer is listed as the only one.

In the background, the Terminal window clocks these choices, but stalls with line "ValueError: need more than 1 value to unpack"

Selecting my new printer and clicking on the Next button (on page 2 of 5) has no effect.
I've tried deleting all printers and re-tracing my steps, but the end result is the same, and therefore I am stuck.

Can anyone throw me a line ?
