Want this question answered?
a printer is a machine that produces a hard copy or a printed copy of your data.
A microphone and a computer mouse has only an output. That is an input device. A loudspeaker and a printer has only an input. That is an output device. A read-write CD/DVD, floppy disk, tape drive, and hard drive are all I/O devices because they can be used to store and retrieve data.
output means the result which we get from the computer it can be in any format,, e,g vedio which we see on the screen sound which we here from the speaker or the printed form hard copy produced by the printer thankx for readin
Optical Code is read on the principle of beam reflection. Initially a beam is made to incident onto the optical code. As the beam gets reflected, it is analyzed for the verification of the code.
It really does depend on your printer. I would sugest that you read your owner's manuel :)
The lazer hits the CD bouncing back the information contained in it to the equipment and relaying it back all the way to the monitor to be read or the speakers to be heard. It is the input output works of the computer.
It depends how you define these terms. Technically it is both, since floppy drives can be written to as well as read from. However, the term 'output device' normally refers to a means to provide information to the user, such as a screen, printer or speakers. Since a floppy drive can not be used to output information directly to the user (only to another computer), it could equally be argued that it is an input device.
They read the speed of the input and output components of the transmission.
It depends on the printer and scanner - go to the maker's website for instructions.

HVPS, give the printer enough charge to put toner on the paper for you to read. without the charge, no print or faded. re: your regular black printer.
