Firstly - I never turn my Canon printer off. To be fair it's the houses 'jobbing' printer that we run on cheap ink from Amazon so it's inking costs are low but the best way to run any inkjet printer is to leave it on and print regularly. That way you minimis the cleaning cycles and waste less ink.
Secondly can I just add that I hate inkjet printers. They are noisy, slow, clatter and bang, run random cycles doing god only knows what, they don't give sufficient warning of ink capacities, spit out duff prints for no reason, cost too little only so the manufacturers can sting you for ink.......I could go on. I will say the Apple gear in the house deal with them better than the Windows gear in that a printer 'just works' without drivers or any installation but the actual equipment itself is still rubbish.
If walked up to your car and the chip thing in your pocket didn't open the door straight away but set the car of clunking and flashing lights at you for a minute you'd go mental. If when you did get in the start button didn't immediately start the car but initiated a warm-up sequence you would drive to the garage and run the salesman over.
If your TV was unresponsive for 30 seconds when you pressed the remote you'd scream at it then more likely than not chuck the remote , the dog, the kids or all of the above at the said tele then stomp off to the pub.
Why then do we accept this sort of behaviour from a printer. Something so simple that all it needs to do is spit a bit of ink onto a bit of paper......a bit of paper that you have to tell it the size, surface, quality, weight and for all I know sex off......I hate them!
And don't just think its home printers......don't get me started of the Fuji Frontier Mini Lab at work. That....that operates on Windows NT and has one insistent beep that will not stop until you figure out what the insane flashing code means and rectify it. One beep! One! All day long it's beep, beep, beep, beep, beep, beep, beep, beep.....water, you want water. Right here's water......beep, beep, beep, beep, beep, beep, beep.......the film hasn't cut. I know the film hasn't cut because it was a loose film in a film carrier and it doesn't need cutting, yes I'll press your button to stop you beeping, yes I'll press it again because you still think I'm not paying attention and yes I'll give you more ruddy water.
Beep!
