Printers

When you make a print of one of your photos on an inkjet printer, a lot is happens inside the printer. As the print head sweeps rapidly across the paper, hundreds of ink nozzles in the head spray ink droplets to form the pixels in your colour photo.

Print head

The print head can have 48 or more separate nozzles for each colour of ink. For example, Epson Stylus Photo has 48 nozzles each for five different colours: cyan, magenta, yellow, light cyan, and light magenta. It has another 48 nozzles for black. Generally, more nozzles increase the printing speed. Different colour dots are overlaid on the same spot. With a microscope, you can see dots look green at the sport where yellow and cyan inks were shot. So you can say that primary colours are mixed in the ink jet coating layer.

Epson

Printer like the Epson Stylus Photo R300 can also print onto CD's or DVD's, producing disks that match the quality of those bought in the shop. This particular printer also has separate ink tanks, so you only need to replace the ink that runs out, generally though they all run out about the same time.

If you look at the way a primitive, four-color ink jet works, it’s easier to understand. Each pixel can have between zero and four dots of colour sprayed on it. Different combinations make it possible to have at least 10 colours. Some printers could also use combinations such as cyan and black, or magenta, yellow, and black to increase the total number of colours to 16

Memory Card

If you also have a digital camera, printers like the R300 come with a memory card slot, which you can use to print your photos with, without using a PC, this particular model will print a list of photos from the card in the forum of small thumbnails, letting you choose which ones to print.

Cartridges

Be careful when buying a printer, some printers sell for less than Ł25 but the Cartridges cost Ł30, so its not always best to buy cheap. Take a look at cartridge prices for the model, see if there are compatible cartridges by another company, as the manufacturers Cartridges can be 3 times more expensive.

Refill

Most printer cartridges can be refilled using replacement ink, you will need a kit for the particular model, it will come with blunt needles, bottles of ink, and possibly a small drill to drill a hole into the cartridges. This can be a messy job, and its not something the average person would do.
