One thing that may not be obvious is that the the 3880 /3800 series can print borderless sheets. However, the more robust P5000 rather stupidly does not support this. It can do borderless rolls which is semi useful. It is disappointing that the prosumer version would have this feature and not the more robust printer. This may not matter to every user, but we primarily use the 17" size machines for portfolios and use larger printers for the everything else. We just added a Canon Pro-1000 as it is the most robust pro printer capable of doing borderless sheets. The rest of my shop is all
Epson so this was not the ideal choice but ultimately necessary.
Vacuum transport vs pin wheel transport. Vacuum doesn't leave marks on the paper (like pin wheel can) and also holds the paper flatter, but it also requires a small part of the paper to hold on to, which is why it can't print borderless on cut sheets like pin wheel can. It's a tradeoff.
