Is your ribbon almost out of ink or dried up? If so, I would suggest replacing it.
The typewriter ribbon is the store of ink for the typewriter. When a typewriter key is pushed the letter springs up and hits the ribbon - pushing the ink onto the page in the shape of the letter.
It all depends on two things: how much printing takes place, and whether the ink on the ribbon dries out quickly. When printing, the inked ribbon moves slowly along so the printing pins hit fresh ink as much as possible. When the ribbon reaches the end, a lever is (usually) moved over to make the ribbon return back the other way. Eventually, after many passes, the ink will fade and the ribbon will need to be replaced. Or, in an over warm office, for example, the ink may eventually dry and not produce a good print, even if the printer is little used.
Laser printers and ink-jet printers don't use a ribbon.
False
you have to go to the typewriter with ink ribbon to save
its usually black but you might be able to get different ink colours
In my opinion, a laser printer is better than an inkjet or ribbon (dot matrix?) printer.
Thermal Printer
Yes there are. They use thermal energy or UV rays to print on special papers.
They need ink to make them work.If there is no ink in it,it will not work.Its the same as asking; Why do pens need ink to work? Its pretty obvious.
No. They use pins or keys to strike a ribbon that has ink on it. The ink is transferred to the paper. These are rarely seen today, having been replaced by ink jet or laser printers.
