Inkjet Printer Cartridges are very expensive. As an example HP inkjet Cartridge 21 costs around Rs. 1500.
So when your cartridge is empty you have three options:-
1. Buy a new Cartridge. ( 1500 rupees)
2. Get it refilled (200-250 rupees)
3. Refill it yourself (10 – 30 rupees)
Now I will show you how to refill an inkjet Cartridge. I am using HP ink cartridge 21(Black) but this method will work with other
inkjet cartridges like (Epson, Cannon ).
For this you will need:-
1. Ink cartridge
2. Black Ink for inkjet printer
3. 5cc syringe
You can get ink for printer from any stationary shop.
Step 1: Fill syringe with 5cc of Black ink.
Step 2: Open sticker of cartridge as shown below
Step 3: Insert syringe into the cartridge and fill it slowly
Step 4: Put cartridge in printer and take some test prints.
I hope this is helpful for you
Remember me in your prayers.

@Zafar Ali
Ink for printers is specific.
You cannot use dollar ink.
Go to some other stationary shop you will find it.
Can you tell me its name or something? Like which shop and what ink etc
Go to some stationary shop, ask for ink for printers
Do they sell Coloured Ink for the Tri-Colour Cartridge aswell?
Yes color ink can also be refilled.
You will get inks of all three colors, and refill them 1.5 ml of each ink in respective section of that ink.
Ink cartridge has 3 openings for three types of inks
