This document provides information about inkjet printers and thermal printers. It discusses the basic workings and parts of each type of printer. Inkjet printers use ink to print and are commonly used in homes and small offices, while thermal printers use heating elements to activate pigments and are often used to print labels and barcodes. The document outlines some advantages and disadvantages of each printer type, such as inkjet printers being cheaper but having print quality and durability issues, while thermal printers produce durable prints but have higher material costs.

3. Inkjet printers
Inkjet printers, as the name implies, use ink to print text, graphics, and images on
various types of paper. These printers are most common in homes and small offices,
through many commercial printing companies use industrial inkjet printers to produce
high quality brochures, flyers and other pieces.

4. Working and parts
XKFK7654.MP4
• Print head
• Ink source
• Pump to push
• Charging electrode
• Two charged plates
• Gutter

5. Advantages and Disadvantages
• Cost inkjet printer are more widely
available and therefore more
cheaper than their thermal
counterpart.
• Image quality even low end inkjet
printers can produce nearly photo
quality images.
• Image durability ink based images
may smudge, stain and run because of
moisture smugies.
• Moving parts it has many parts that
move.

6. Thermal printer
Thermal printers use tiny heating elements to activate or transfer pigments. Industries
thermal printers are used most commonly to create labels, bar codes, shipping labels
and other heavily used items.

7. Working and Parts
GOAOE7968.MOV
• Thermal print head
• Heating point
• Thermal paper
• Feed roller

8. Adavntages and Disadvantages
• Durable labels and signs created with
thermal printers last longer and stand up
to a wider variety of weather condition
than those printer with ink.
• Less maintenance with fewer moving
parts thermal printers tend to last longer,
are easier to maintain.
• Cost the specialty materials used in
the thermal printer process are
considerably more expensive than
their inkjet counterparts.
• colour choice thermal printer prints
in few colours only because all the
paper contains single colour.
