I recently had a windows update and since then my printer will not print. Say firewall blocking printer. When I'm on the printer program it says network not connected but on windows it shows it as being connected.
I had the same problem with Windows 10. After the Windows update the printer wouldn't print from my computer while the printer still worked fine on other computers. Turned the fire wall off. The printer shows on the add printer list and is highlighted green but it can't be selected!
Screwed around for hours trying Windows and Brother trouble shooting and after a while I noticed that low and behold one of the trouble shooter had the printer print out the printer data info so the computer can run the printer but I suspect something in the update is hiding the printer from normal printer access!
Tried going back to the saved states before the updates, May 3 and 5, 2017 I think but neither would work. Complained about a file problem I think.
Just been waiting hoping Windows will have enough complaints that they will send out another update that will fix the problem.
