You just need to take the cartridges with you, the refillers know which ink is needed.
And if you need to print like 3000 or more pages, i recommend you buy a refurbished HP laser printer. My friend bought HP 1100a printer/copier/scanner 3 in 1 for Rs 5200, but if you need only printer it should be like Rs 3000. Its a lot more economical than inkjet (2000-2500 pages per cartridge) but it prints only black and white.
