Off topic: HP has instituted new software that blocks after market and

HP m277dw is a color laserjet printer, and doesn't use ink cartridges as in inkjet printers.

BTW, I just noticed that HP released a new Full driver for m277dw on 31 Aug 2016. There are new basic drivers as well.

And my sister phoned me today the m277dw went offline again, even when using a USB flash drive to print locally.

Is this m277dw a very problematic device?
