@xin-li The price was including the posh expensive hahnemuhle paper I bought. I think it would be cheaper with other paper. The A3+ brilliant museum matte paper I got free is £50 for 25 sheets. I think it's hard to work out ink prices exactly but I was doing just monochrome prints for my portfolio recently using the black and got around 12-14 prints before the black ran out. It's £12 for a ink cartridge so I figured 80p-£1 for ink for each print. Posh matte paper (308 gsm) is £3.20 per sheet. The other matte paper (300 gsm) I have is £2 per sheet making it about £3 per print. The printer cleans itself when I turn it on, I've not experienced any clogging but I've only had it a few months - I too was feeling the pinch from paying loads for fine art prints.
The larger model Canon imagePROGRAF PRO-1000 I looked at is about £500 to fill with 12 pigment inks - the cartridges are much larger though. it prints up to A2.
Main thing is to not buy a dye printer as the prints will fade fairly quickly, especially if exposed to sunlight.
It's one of the best things I ever bought and loving seeing my digital work on paper. Brings it to life. I can also do collage stuff now. I make large prints on A3 tracing paper taped together from pencil drawings I do. Makes it easier to make a large painting or stencil work. It's just opened up a whole new area of art making that was missing from my art bag of tricks.
