A local charity I volunteer at has just upgraded its 2 main office desktops to Windows 10. The dozen laptops they have for client use were upgraded a while ago.
One of the office pc's has a USB connected printer that was shared so all the other computers could use the printer. I think that PC is now Win10Home.
The Win10 upgrade bolloxed up the printing and I had to re-install the printer on all the other computers.
This went fine till I got to the last two. They just dont recognise the computer or the printer. I used the option where you type in \\computername\printer for connecting.
That was Saturday. I went back in today and they still wont detect the shared printer.
Why would something work perfectly fine for 1 desktop and 10 laptops and then consistently fail from that point onwards?
There is no domain or Homegroup, just a bunch of computers on a network.
Any suggestions for a fix would be most appreciated.
