Ink jet printers form images on the paper by
which of the following methods?
1. Spraying ink on the paper through a
stencil to form the character
2. Spraying ink on the paper with the print
head moving to form each character
3. Spraying ink on the paper in a series of
dots to form the characters similar to a
dot matrix printer
4. Electrostatically charging the paper to
attract the ink to the proper position to
form the character
The ink in an ink jet printer is sprayed onto
the paper by which of the following
methods?
1.

3.
4.
By using a pneumatic pump
By using piezoelectric crystals to
squeeze a nozzle tube
By using small heaters to expand an air
bubble and force the ink out of the
nozzle
Either 2 or 3 above, depending on the
printer
