What are the disadvantages and advantages of a serial printer? Who elaborates on it Thanks!

Pin printers are mainly for printing invoices, bills, cash registers and other tickets.

Advantages:

One, the low cost of printing (if the ribbon frame is not a problem, generally change a ribbon five to ten dollars, if the ribbon frame is also twenty or thirty dollars)

Two, print multiple self-repeating print paper (this print paper is mostly for the cashier to use, the paper on both sides of the self-hole, clamped in the back of the pin-type printer automatically feeds the paper, and the mobile billing to play the (This kind of paper is mostly for cashier use, the paper comes with holes on both sides, clamped behind the pin-printer and feeds automatically, which is the same type as the mobile phone bill).

Disadvantages:

One, the price is high. The cheapest pin-type printer is probably priced at about one thousand two hundred and thirty, and is A4 format, or drum (pin-type printers are divided into flat push and drum two kinds).

Two, slow printing speed. Because the needle printer is aimed at hitting the invoice, the general invoice will not have too much text, so the speed requirements are not high.

Three, noise. Because the needle printer is used to hit the way to print, so it will produce a large noise, very unsuitable for home-based users.

I would like to emphasize that pin printers print in monochrome, but not only black!
