I have a Brother HL-3170CDW and have been using it with a HP Chromebook to cloud print.
It has worked great for over a year and about a month ago, just stopped cloud printing. I have unregistered and registered it. I completely reset it. I have called Brother and they say it is a Google problem. I really don't think that it is a cloud problem as I can see my prints queued on the cloud print.
I have had some success using the printer with my desktop (Windows 10). This doesn't make sense to me as I can see them queued up- they just won't go to the printer!
Any ideas on how to get this Brother printer to work again with the Chromebook?? There must be something in the driver for the Brother that is not right.
