Why Am I Getting Error Messages When I Print a Document on Linux?

CUPS

Episode 1794

Guy from Mobile, AL

Guy recently put a new hard drive in his computer and he put Linux on it. But now when he tries to print he'll also get several additional pages printed out for no reason. Leo says that Linux uses an open-source printer driver called CUPS and it's printing out an error code that it doesn't understand. It's probably due to CUPS using a printer driver that is close, but not exact to the printer. Try and see if the printer manufacturer has a Linux driver. That could help. Or see if he can use a different HP driver since HP uses PCL, which is good on Linux. Give it a shot, paper is cheap.

How Can I Prevent a Neighbor From Taking Control of My Apple TV?

 Apple TV

Episode 1794

Jeff from Pasadena, CA

Jeff lives in a condo and he has a problem with his neighbor taking over his Apple TV (she has one too). Obviously, a remote from the neighbor's Apple TV is taking control. How can he prevent that from happening? Leo says to go in the settings, under Airplay, and turn it off. Settings->Airplay->Allow Access-> Allow nearby. But that may not prevent the remote from taking over. Leo recommends moving Jeff's Apple TV as far away from the wall as possible. Or, if possible, he could try and place a metal tray or sheet behind it to block the signal. 

Can I Connect Four Monitors to My Computer?

Dell D3100 Docking Station

Episode 1793

Mark from Oxnard, CA

Mark would like to connect up to four monitors on his laptop. Can he connect two by USB? Leo says that it will work. There are a lot of USB monitors out there. But there may be a limit that the video processor can push pixel-wise. So it depends on your video card. Look at your specs. And if you are using an external GPU, you'll need a driver to do that as well. But don't go above 1080p. That'll help. 

Will Cars Get Better Battery Life Soon?

Tesla 

Episode 1792

George from Santa Monica, CA

George keeps hearing about new Tesla car battery technology that promises a million miles before replacing. Leo says he'll believe it when he sees it. There are always stories about new battery technologies that promise great things but are short on delivering. However, the battery capacity is getting better every year and the range is improving as well, so he may have to charge less often, and when he does, it'll be faster to recharge.

But a million-mile battery? Not likely.
