Inkjet printers are very common for most home users of computers as
they are cheap to buy and can print in both colour and black and white.
An inkjet printer works by accurately moving a print-head over a piece
of paper. As the print-head moves of the paper tiny jets of coloured
ink are sprayed onto the surface of the paper: this is the 'ink jet'
which gives the printer its name.
The main problem with inkjet printers is that they are quite slow and
they a fairly noisy.
