today i have learnt the difference between a ink jet print a laser printer and a dot matrix printer and there properties
- A ink jet printer can produce 2 – 8 pages per minute (ppm) and it is the slowest out of the 3 main printers and in the picture below it show’s the colours of inks. average cost is £45

- A dot matrix printer has pins inside the printer that strikes the paper with ink on it and makes a dot and it does it so many times that it starts to make letters or numbers by making a load of dots and you can make anything with enough dots even a picture and it can print 2 – 10 . and can cost up to £5000

A lazer printer uses a sort of roller that has toner on it and the printer puts the toner onto the roller and the roller pushes the toner onto the paper with extreme force and the toner gets pressed into the paper and can print 8 – 200 pages per min and the colours this uses are cyan, magenta, yellow and black.(C,M,Y,K) and costs up to £ 900
- The total cost of ownership of a printer is:
- initial purchase price
- cost of supplies, such as paper and toner
- price per page
- maintenance costs
- warranty costs
- the amount of material to be printed
- The expected lifetime of the printer
