If you want a 16" printer you have few choices. And the reasons for choosing one over the other will depend on your circumstances. The review provides enough information for you to be able to make an informed decision because there's no clear "printer a is better than printer b"
You have (afaik) 3 choices at 16" (A2) for a desktop printer.
Canon Pro-1000 which has a 40" limit on panoramas and no roll paper holder. £1k
Epson P5000 which is practically unlimited on panos, cheap on ink, and huge. £2k
Epson P900 which has a (purchase separately) roll paper holder, smaller tanks than the P5000, is smaller than the P5000, and will print 10ft panos. £1k
Difference in print quality is arguable (on the internet) which probably means you need a magnifying glass and/or colour reference charts to determine. In other words - to me - they're all the same when it comes to colour gamut even though the scientists will argue it's not.
For me, the Canon is out because if I want to print a 3:1 pano at 16" I can't. Simple decision.
I have the SP4800 which has the same footprint as the P5000. It's massive and I can't move it on my own. However with 200ml tanks the cost per print is probably the cheapest out there at 40p/ml vs 60p/ml for the P900 and the Pro-1000.
The P900 is a really nice middle ground option for me and at £1k is a much cheaper investment.
Your mileage may vary though, hence the review being useful because it gives you the information you need to make the right decision.
It's fun to watch
