number of dots per inch
A dot matrix printer creates characters by
striking pins against ink ribbons. Each pin

most dot
Matrix printers ranges from 350
to 1100 characters per second

9. Line printer is type of

but better in quality

a resolution of 600 DPL
or more. Its price is less
than laser
printer . Most inkjet
printer can
print from 10 to 35
pages per
minutes
