What's the difference between fountain pen and cartridge pen?
A fountain pen has a vacuum system to pull ink into an internal chamber.
A cartridge pen is a fountain pen in which the ink is held in a replaceable cartridge.
Thanks for all of you. It's quite clear now.
I don't think 'cartridge pen' is the name for it, just as you don't call a printer, a 'cartridge printer'.
It's fountain pen which uses refillable ink or replaceable cartridge ink.
