Can this printer print out using only black ink?
I was ever using EPSON printer.
It uses color inks while cleaning even if I am setting to use only black ink for printing.
I had to buy color inks although I did not print colors at all.
I heard that I do not need color inks in the case of HP printer.
But, I heard also that it is impossible to use black ink for cheap HP ALL-in-one printer.
Does anybody know? What about 4215?
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
