As a temporary fix
i removed all installed printers
uninstalled hplip

http://hplipopensource.com/node/188

download the automatic installer from hplip

http://hplipopensource.com/hplip-web/downloads.html

and while executing the installer, when i was asked if the ubuntu distribution was 16.10, i answered "no" and in the following menu i set "operational system = ubuntu " and on "distribution" = other, the installer then set ubuntu 0.0 as operational system and it continued with the "make" = "make install"

i configured my all-in-one printer (printer-scanner-fax) and restart H/Y

Still the printer was not working, it gave an error regarding "foomatic-rip-hplip"

but the scanner and fax function was working

so through "synaptic package manager" i marked hpcups (package:printer-driver-hpcups) for reinstallation, and gtklp and libnet-cups-perl for installation, (although i dont think that gtklp and libnet-cups-perl was necessary)

restart system

after that the printer was working properly with the cups module, and fax and scanner with the hplip module

The proper fix would be for HPLIP to release a distro that is supported in ubuntu 16.10, (it was clearly stated in the installation that hplip is not supported in ubuntu 16.10) but after the upgrade in ubuntu 16.10, i found no other way for scanner and fax driver to work.
