As far as I am aware the 13 inch (A3) printers all use small ink cartridges that lead to them being very expensive to run - although this may not be too much of an issue if you only do a small amount of printing. It may be worth checking all the Canon, epson and HP offerings at this sixe (the HP B9180 got some good reviews, but I've not tried it)
The 17 inch printers are all capable of excellent output.
- Canon offers the IPF 5x00 printers that can handle both roll and sheets well, offer excellent ink economy and (in my experience) no clogs that aren't dealt with by the printer automatically. Downside is that the heads are very expensive if they fail. I had one go down inside 2 years, but well wihtin usage expectations. I think this is actually more common on lightly used printers from talking around the issue. That led to me replacing the printer. It will print on glossy or matt surfaces with no ink switch.
- Epson offer the 3800 for sheets only which offers cheap ink switch between glossy and matt black and 4800 for tolls and sheets (1 at a time I think?) which uses a lot of expensive ink if you switch between glossy and matt paper. I'm not sure where they are with the x880 and on versions of the these printers as I've not needed one for a while.
I'm currently using an HPz3100 (24 inch, mow replaced by z3200) which is excellent on roll and large sheets, but doesn't feed A4 very well - usually takes a couple of goes to load straight.
For gloss paper, I use Ilford Gold Fibre Silk as may mainstay now, with some rolls of HP premium instant fry satin as a cheaper alternative. I've also use Hahnemuhle Photorag Baryta and Pearl, which I really like but are expensive. I didn't like the Harman FB Al gloss, finding it too blue bright and the image somehow too 'crispy'.
For Matt paper I like the hahenmuhle Photorag bright white, fotospeed (innova, permajet, James Cropper) High White Smooth 315gsm cottn rag and also have some HP Matt Litho Realistic, which is quite warm but nce for some images.
Hope this helps, mostly don't worry too much about the output for the high end printers so much as the abiulity to feed what paper you like. Also, make sure you can make or can get access to decent profiles.
