After buying a new inkjet printers on practically a yearly basis (I'm not making that up), I decided to move to a laser printer b/c I have terrible luck with Inkjets. I go for long periods of time not using the printer (probably why I had issues with the Inkjets). Is anyone pretty knowledgable about printers? I want advice on whether I should shut it down in between print jobs or is it ok to leave on all of the time?
