You will always wish you had a printer that is one size up from the one you got. Until you get to 44". Or maybe 60".
Wow, I had a 7800 and then a 9880 and my everyday relationship with those printers was as emotional and up and down as anything you read about in the National Enquirer. I am sure that will come as a surprise to so many people here.
Bottom line, I could make those printers do what I wanted, but sometimes I had to get rough. The bottles of Windex and distilled water were never far away, as was the roll of lint-free blue Scott towels. And I knew how to use them.
I honestly don't think down times in the range of 1 or 2 weeks had much effect, but don't stretch it out too far without a narrow tray of water tucked up in the head parking area, which you must remember to replenish. And keep your docking station and wiper blade in good order. But as the memories start to return, I just realized that if I needed to replace my printer I would rather take out a mortgage on the house and buy a new Canon iPF than save some dough on a used 7800. It was all too S&M.
However, the prints that crept out of that 7800 could not be faulted, except for pilot error. Their only offence was that sometimes they weren't as big as I would have liked.
