How do ink cartridges work?
I am thinking to buy a printer (hp deskjet ink advantage k209g). When i see the printer specifications, i see that it supports hp tricolour cartridge. It has three colours. How do i print pages which are having colours other than that in the cartridge ? Please help me soon.
HP was known for good printers. Lately they’re know for expensive printers and even more expensive ink. HP is the only company which:
1) puts an expiration date in the chip of the cartridge. You can insert a new sealed cartridge and have the printer reject it because it is expired
2) changes the size of the cartridges to make them smaller but keeps the same model number. You buy a cartridge at the store which is the same model your printer came with only to discover the cartridge wont fit because it is the other version.
I won’t even go into details on their terrible tech support, run by Indians with thick accents who read off a script and can solve nothing.
There are a lot of HP fans who bought their printers years ago when they were still good. It will take a while before people realize how much worse the company has become.
As for having all three colors on one cartridge, this is also a bad idea. Assume the cartridge can hold 20 ml of ink. Now it has to hold 3 colors so you are lucky if you get 6 ml of each. Then if any one of them runs out, the whole cartridge has to be replaced. What a waste. With individual color cartridges you get 20 ml of each color and you only replace the one which is out.
Epson wins for best price/feature comparison, best warranty and lowest cost of ink. You can’t beat their warranty. If anything goes wrong, they will fedex a replacement and pick up the old one at their expense. You can get ink for under 50 cents a cartridge at www.ccs-digital.com. You pay under 2.50 for reusable cartridges and then get $2 back for the empties. Or you can buy refillables (which is what Im using now) and refill yourself for pennies. Take a look at the workforce 3520 and 3540. They have received rave reviews from people who bought them.
The cartridges contain the primary colours, so they print different amounts of the 3 colours depending on the colour they want to create and then combine them on the page.

Personally a bit of advice on any device which uses SHARED cartridges providing 3 colors, if one bit empties the cartridge will misprint colors meaning a lot of expensive ink ends up wasted.
Preferably get something with either separate cartridges or go for color laser. To keep running costs as low as possible.
Next how it works, they simply fire 1 color or 2 or more colors onto the page – which results in a mix – thus you get all the colors, most printers can print ALL 16m colors thats a lot of color from just the basic 4 the printers normally hold.

Inkjet cartridges are extremely popular: most computer users are familiar with inkjet printers, as they provide relatively high quality printing and can be used in a variety of industries. The principle which inkjet cartridges use is very straightforward and easy to understand. Inkjet cartridges are reservoirs of ink which connect to a series of small nozzles called the print head that are used to create very small dots of ink. In a single color such as black, the nozzles can be used to form text. The colors in the inkjet cartridges can also be combined to form a color image.
Most color inkjet cartridges follow the Cyan, Magenta, Yellow, and Key, or Black (CMYK) color model. The four colors are held in separate reservoirs, sometimes within a single cartridge and sometimes sold individually as separate inkjet cartridges. They can be mixed in specific amounts to form hundreds of potential colors, creating lush and evenly toned color images on a wide variety of papers. When a user prints a document, the data sent from the computer to the printer includes the specific CMYK formula for each pixel in the image and the print head replicates it with hundreds of tiny nozzles that fire simultaneously.
