The data goes to the printer so it is an output device.

An inkjet printer
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Managing data refers refers to tho the receipt, processing, retrieving and the storage of data.
Signal Element Versus Data Element: Let us distinguish between a data element and a signal element. In data communications, our goal is to send data elements. A data element is the smallest entity that can represent a piece of information: This is the bit. In digital data communications, a signal element carries data elements. A signal element is the shortest unit (time wise) of a digital signal. In other words, data elements are what we need to send; signal elements are what we can send. Data elements are being carried; signal elements are the carriers.
A daisy wheel printer "outputs" data sent to it from the computer and prints the data on paper.
Printer firmware is a program inside a printer, that allows it to receive data from a computer and so print on paper.
A printer buffer is a temporary storage area in a computer or printer that holds data before it is sent to the printer for processing. This allows the computer to continue operating and sending additional print jobs without waiting for the printer to finish the current job. By managing the flow of data, a printer buffer helps improve printing efficiency and reduces the risk of data loss or bottlenecks in communication.
Every pixel of the picture is stored in the computer as a stream of data. The data tells the computer (and subsequently the printer) what colour and how bright to display (or print) each pixel. The hardware inside the printer (and the circuitry in the cartridge) converts the data into instructions for the printer cartridge so it uses the correct mix of colours to generate the printed photograph.
All printers generate print, as printing is why we use a printer! Basically, data, with format instructions are sent to a printer from a computer, or similar device, and a printer translates the data and prints the results on paper. Apart from the hardware (printer, computer), software and printer drivers make the hardware work properly.
