Heat sensitive paper is passed over a single line thermal head having a heater element for each of the 1728 (A4) picture elements.
A typical method of operation in a thermal printer is at the start of reception to step the paper back from its normal guillotine or tear off position, so that the start of the page is under the thermal head. To avoid having a driver for each element the head may be electrically divided into sections for printing in a matrix. The data is latched into a section and printer in 1 to 2.5ms. When all sections of the line are printed the paper is either advanced 1/3.85mm for a standard line or 1/7.7mm for a fineline.
A standard line may be achieved by printing 2 identical fine resolutions lines. The print energy required is about 1/4mJ per black dot, at a temperature on the paper of around 90掳C. Print times of between 5ms and 20ms per line are typical, with automatic compensation for ambient and head temperature by varying the supply voltage or the print pulse time.
Thermal printers have a head that consists of a row of tiny heating elements. The paper has a special coating that turns dark grey when it is heated. By turning appropriate elements on or off as the paper passes the head, the computer can print characters and designs. Thermal printers are inexpensive and silent in operation. They are often small, printing out on paper tape a few centimetres wide. They are often used in supermarkets and shops for printing out the bill. Their main disadvantage is that the printing fades with time and may be obliterated by excessive heat.
The head of a dot-matrix printer consists of a vertical row of nine fine needles. A coil surrounds the base of each needle and the needle is propelled toward the paper when the coil is energized. As the head travels along a horizontal track, the needles impact an inked ribbon, causing the paper behind the ribbon to be marked. The head scans across the paper, printing a row of characters. Then the paper is moved on to print the next line. Dot matrix printers are usually limited to printing in black. They can print on almost any paper, and on separate sheets, though continuous perforated paper edged with sprocket holes is commonly used. Their main disadvantage is that they are very noisy. Under computer control, they can be made to print in a wide range of fonts and can also be programmed to print simple graphic designs.
At one time, dot-matrix printers were the commonest kind of printer used in offices, but more recently they have been replaced by the inkjet printers. The head of an inkjet printer works by squirting microscopic drops of ink at the paper as it scans across the sheet. These printers are very quiet in action, though not silent, are reasonably inexpensive, and have the big advantage that they are able to print in full colour. They print on separate sheets and on any paper surface, though special paper with a gloss surface is best for printing colour photographs.
The head of the printer is perforated with between 200 and 1000 pinhole nozzles, about 70 渭m in diameter. They are in staggered rows spaced only 80 渭m apart so as to give the printing a high resolution of 600 or more dots per inch. For colour printing, the nozzles are in groups supplied with inks of four different colours. The inks are coloured cyan (blue-green), magenta (red-blue), yellow and black. The first three are the subtractive colours that, when mixed in varying proportions, can produce all the colours of the spectrum in all shades from pale to dark. It is preferable to print true black using black ink, rather than using a mixture of all three subtractive colours.
Behind each nozzle is a compartment filled with ink (A). At the rear is a thin wire which acts as a heater. To eject a drop, a strong but short pulse of current is passed through the wire (B). The heat causes a bubble of vapour to appear around the heater. The extra volume of the bubble produces a pressure wave which forces a jet of ink out through the nozzle. After the pulse the bubble contracts (C) and a tiny drop of ink breaks away from the jet. The drop rounds itself off (D) until it is a perfect sphere as it hits the paper. All of this takes place at high speed, so that about 12 000 drops come from the nozzles of the heater in one second. In some printers, up to four drops can be directed at the same point on the paper. This is equivalent to having drops of variable size, giving a graduation of the tone of each pixel.POS Accessories Made in China
