HP Deskjet printer buying guide

I have an hp photosmart C4480 printer for my laptop, and i have the wire that plugs in from the laptop to the printer, and the power adapter box thing that connects to the printer, but there’s another wire that plugs into the box that goes into the wall, and i’m missing it. is there any way i can make my printer work without having it plugged into the wall? or is there somewhere i can buy the cord?
thanks.

As well as the USB cord that connects my laptop to my printer. My printer is an HP photosmart C4180 All-in-One and I have been searching the HP website and cannot find a way to buy replacement cords, anyone know how I can get new cords?

i have the usb cable, just not the plug that goes from the printer to an outlet….i can’t find it on any site!! will an office supply store have it?? helpppppp

I bought a HP photosmart 335 printer but it didn’t come with a power cord & adapter. The manual states it is a 100 - 240 V AC (+- 10%) 50/60 Hz (+- 3 Hz) adapter. The power supply model number is #0957-2120. I have a power cord and adapter from another device (Camcorder) which is 110 - 240 V. Can I use this one safely ????

I have a HP photosmart C4380 printer scanner, I have a 3 pin power cord plus a specialized HP power plug that fits into the back of it. I have just plugged it in, the light on the power cord is on, but when I press the power button on the printer it won’t switch on, is there a way to get it on?
