Printers create output by striking an inked ribbon against paper using metal pins, making them useful for printing on pressure-sensitive forms.

dot matrix printer

Explanation:

Dot matrix printer, sometimes called impact matrix printing, prints from a collection of dot matrix data to a device.

Types of dot matrix printers

1.Impact dot matrix printers

2.non-impact dot matrix printers, such as inkjet, thermal, or laser printers

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
