I had a cheap Epson all in one printer and was always having to clean and realign the heads. Wasted loads of ink.
I exchanged it for a Cannon MG630 and it's been problem free when I (infrequently) use it. So much easier.
One tip though. Always leave your printer powered up. Turning it off will more likely cause issues.

YES, another great tip! I left my epson printer on all the time, to prevent the heads from drying.
