Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

computer shuts down when Samsung printer is plugged in


I've been shopping around for a while for a new printer.
Today I was loaned a Samsung Xpress C460W all-in-one printer, which I thought would do as a stop-gap.
I plugged it in and turned on the computer, but the tower cycled on and off several times (not booting-up, just on and off) before I guessed the printer was the problem and unplugged it.
I then tried starting the computer, and once it was booted up, plugged in the printer, and it promptly shut down and then recommenced flicking on and off.

Frankly, I may bite the bullet and buy a new printer rather than spend a lot of time worrying about this Samsung: I would prefer a simpler printer rather than an all-in-one, and I've spent to much time lately in blind alleys. But I would always prefer to see things work (which probably explain why I spend so much time in blind alleys. . .).

And I am very curious: do Samsungs have a bad track record with Linux?

I am running Mint 19 Cinnamon on a Lenovo Thinkcentre.

Hi Brant,

Sounds like a hardware issue. If your computer won't start when the device is plugged in and promptly turns off when you plug it into a running session, I would suspect either the USB port (assuming this is a USB printer), the USB cable or the printer being faulty.

You could troubleshoot by plugging some other USB device into the same port (if it works, that eliminates the port as the problem), try using the cable that came with the printer with another device you know usually works (this will tell you if the cable is the problem) and finally, if the previous step is yields positive (cable is good), try connecting the printer with another, known-good USB cable. If it works, that will indeed be mysterious ( ... ...) ... If it doesn't, I guess the printer is faulty. Finally you could try plugging the printer into another system and seeing what happens.

This is all basic, physical, troubleshooting.

You could also take a look at your linux logs (with journalctl and dmesg) and search for statements explaining the shutdowns ...

Let us know how you make out !

No, Samsung don't make crap. Many exotic and catastrophic possibilities spring to mind, but what you can do is limited. USB sockets have power limits, and you give us little information. Basically, a usb 3 socket has a higher current rating than usb 2 (iirc) which in turn is higher rating than usb-1.x.

change things out: the cable first, the usb port, the printer after. If another printer (or hd) works on that cable, the cable is good. If there are electrical short circuits you can blow things.

I plugged the printer into my laptop for a cross-check, and was startled when my desktop promptly turned off!
That was when I woke up and realized it was not the computer or the OS at issue, but rather the Tripp-Lite power supply I had connected the printer into. Using another plug solved the problem.
Perhaps the Samsung drags an unusual amount of current at start-up?
Apparently the printer works well with its regular system, but I'll play safe and buy something better suited to my needs.

I did see this on another site, that I thought was well put:
"The relationship between printers and PCs has long been fraught with difficulty."!

Yes, laser printers draw a large amount of current when first turned on or printing and therefore plugging them into a UPS or surge protector is not recommended. It is also recommended to plug them into a separate circuit from the computer.

This is a problem with all laser printers and not just Samsung.

I think I should point out that this advice is only relevant if you live in North America, Central America, or Japan. In the rest of the world the much higher voltage allows the normal domestic power socket to deliver 3 to 4KW rather than 2KW.

This is true...

Oh well, now I know.
My old printer was an HP 1215 laser printer, and never had problems; I guess the Samsung is just greedier.
I had decided that I would like a monochrome printer, and after extensive shopping around, discovered they are surprisingly rare; I also preferred a single-function printer, and they also seem to be rare. I finally walked into a shop that was selling out, and bought a Canon Pixma for what seemed a bargain--ie, neither single-function, nor monochrome!
Man proposes, chance disposes.

A different plug would have been my recommendation. But you've already discovered that.

I recently got a samsung laser printer (used). It's 300W's according to the back of it. And kind of scary as the paper comes out fast and smoking(steaming) when it prints.
