6. Connectors

The connectors are the most essential amongst all the parts, as it the only medium that lets the power supply in, and the only medium to send the computer’s printing commands in to the printer as well. The connectivity, again, depends on the type of the printer device.

10. Print Head

Print Head is another most essential part of the printer, which has the job of delivering the ink from the printer cartridges on to the surfaces of the paper. When the printer receives commands from the computer device, the printer prints the contents on the paper, while the Print Head is used for picking the ink and placing it on the paper.
