Whenever we make a purchase at a shop or at a supermarket, more often
than not, we see a little printer next to the cash register at the
checkout counter. That little printer, called a
Thermal receipt Printer,
prints out receipts, and is a minute detail in an elaborate system
called point-of-sale system or POS. Have you ever wondered how a Thermal
receipt Printer works?
As its name implies, a Thermal receipt
Printer is dependent on heat. It makes use of a special form of paper,
called thermal paper, and a ribbon with solid "ink" or resin with a
polyester film backing. When you open a Thermal receipt Printer ,you
will see the rolled thermal paper nestled within, just beneath the
printer head. Sandwiched between the thermal paper and the printer head
is the ribbon.
When the Thermal receipt Printer is used, what
happens is that the printer head generates heat. Just what pixels or
dots are heated on the printer head depends on the characters that are
being printed. The heat is then transmitted through the polyester
backing of the ribbon, and it causes the resin or the "ink" on the
ribbon to melt. When the "ink" melts, it comes into contact with the
thermal paper to form the characters.
The ink on the ribbons used
on Thermal receipt Printer are not really ink. This substance is often
made of wax, a mixture of wax and resin, or pure resin. Ribbons made
with pure wax are the least durable of the three, and they are often
used to print out barcodes and labels. Printouts made with pure wax
ribbons are not expected to last more than a few years and must always
be protected from moisture.
Ribbons made with mixed wax and
resins are a lot more durable than those made of pure wax. They are used
for printing finer images on smoother paper, or on film-coated paper.
Despite their increased durability, printouts made from Thermal receipt
Printer using ribbons with mixed wax and resin should still be protected
from moisture and chemical exposure.
Ribbons made with pure
resin are not used for POS and checkout systems. They are for printing
on plastics. The printouts made from these ribbons are the most durable,
and they require minimum protection from chemicals or the
elements.Thermal receipt Printer are simple machines that work using
simple processes. And yet, they are a minute but definitely essential
detail in an entire POS system.About more the receipt Printer
