Most biometric devices would be input devices although they may also utilize storage devices and output devices in their functioning.
A biometric device usually takes in biometric information about a person and compares it to information stored in a database - much like username/password methods of authentication compare the username and password to the stored information for a user. Fingerprint scanners, read the fingerprint, convert it to a data stream and then compare it to the stored data previously recorded for the individual, retinal scanners read information about the retinal patterns of a user, convert it to data and compare it to stored data, etc. Note that biometric devices must rely on a storage device, but usually the storage device is not part of the biometric device. Instances of OUTPUT associated with a biometric device might be a signal to open a door or trigger an alarm, but again, the output usually comes from another device that the biometric device is connected to.
Is a printer an input output or storage device

Disk drive storage can be both an input and an output device.
Pendrive is not a input device nor output device IT is STORAGE DEVICE. storage device, only data can be saved in pen drive.
no its storage
a CD is an output device that can be used as a storage or input device
A CD is a storage device.

A Flash Drive can be an input, output or storage device. Hope this helps.
A blu ray disc is a storage medium, not an input/output device.
