Bro, I am talking from my experience.. Don't take the sales Team's Marketing words seriously..
Yes, I am talking about ink-tank printer (Canon G3010) only. The experience was NOT as bad as old inkjet printers, but not as smooth as laser printers as well, obviously. It will work OK, if we take 7 pages of colour print outs every week. Else, you may have to do some occassional maintainence by (Mine is Win7)
Sometimes, even after taking regular print outs, the printer may act a drama and we have to follow the above steps. May be they have written a program inside the printer, that if some minimum quantity of ink is NOT depleted within a time limit, force the customer to waste the ink. But at least after all these stupid things, the printer will work without any issues.
