Does anybody know where in the Cups system/docs/website I can find a list of printers supported ?

Because I would like to buy a printer once only, if at all possible!!!!

Apart from which, what's the point of having "documentation" for a printer-control software, that doesn't tell which printers are supported ?

TIA!

try
http://www.openprinting.org/printers
http://www.openprinting.org/drivers

or from your computer
http://localhost:631/

click administration then add printer
and look on the list on the second page

It's funny but I just went through all that today in reality... but initially I bought a Kodak wireless inkjet, and while a couple major distros came close to its driver, none had it. However, I found out through the gracious folks of Puppy Linux that it's a very true fact that one of two printers are almost completely covered in Cups or elsewhere as for the drivers for them and they said "HP" and "brother" printers are the best choice to go with if you most likely want a driver waiting for you when you get home with the printer and set it up. Indeed I bought a nice Brother laser jet printer after returning the crappy Kodak back and sure enough, on the first try Ubuntu nailed the exact driver for it...

I suggest one of those two...
