Having moved from the 3800 which had a permanently blocked magenta channel... (I've tried it all over the last year) I got the p800, this review was helpful in making me press the trigger.
So far I'm delighted with the printer, some thoughts, reflections and questions...
1. When setting up a custom paper size setting I was surprised to find that the p800 permits a border of 0mm on custom sizes. I wondered if this indicates a higher degree of accuracy in the operation of the print head. I was pleased to see this as it means I could print close to the edge of the custom size.
2. I experimentally printed a square image from my iPhone over WiFi. The default behaviour was to then stretch the image to print borderless, in my case on A4 paper. The image had insufficient resolution so I ended up with a poor borderless image. As I had intended to avoid borderless printing because of the mess it made to my 3800 I was a bit irritated and worried about ink mess inside the printer. Exploration of the ink pads on the platen with my finger didn't find any ink. Instead the end of my finger was just picking up some light oil. Maybe I'd need to print more borderless prints to see the overspray appear. I wonder if the overspray is less with this printer.
3. :-) There is a dedicated iPhone app for printing direct to the printer I discovered after doing this.
4. Prints are substantially more impressive than those printed with the 3800, a big upgrade. I'd read that the 3800 to 3880 difference wasn't that big, similarly from 3880 to p800, but two jumps together is impressive. One image I printed has a strong orange object on silver, the print looks amazing on Hahnemule matt paper, like a hexachrome print.
5. Initially I found the front loading of anything other than a few papers to be very irritating at first, initially the loading process seemed onerous, but wasn't so bad after a couple of goes. However it isn't convenient that you can't print sheet art media of any reasonably thickness from the sheet feeder. For some of my uses I want to print sheets not from a roll as I make hand made books and for cost reasons wish to use paper manually cut from a 24" roll so that I get 17" width sheets with the grain running in the short direction. Hahnlemule art paper with short grain is up to 3x as expensive as long grain. I can't understand why the sheet feeder cannot accommodate a matt art paper of the same weight and thickness as a standard heavyweight matt paper. I'm going to try working around this by selecting the same setting as for my heavyweight matt paper and then custom setting the paper thickness etc. in the driver settings. I can't see why this won't work. Anyone think this won't work?
6. I really like the way that the paper output support is separate from the printer front door. My 3800 front door eventually became worn from opening and closing and it looks like the p800 is more sturdy.
7. Overall the quality level of the printer and its output appears well improved. The size of the printer is compact for a machine that can print a decently large print.
