There is a new printer in da house.
The lop sided ink usage and limited paper choices of the Pro 9000mk2 finally persuaded me to upgrade to the 10s (actually, the successful clear out of my old cameras gave me some cash to splash, which helped get the ball rolling).
The new machine has several benefits;
It is cheaper to run by at least 30%. The tanks cost $18 au. as opposed to $33 au for the older one. It will also likely use the inks in a more balanced way. The useless Red and Green tanks in the Pro 9000, that make buying full sets of ink a wasted benefit* have been replaced in the newer printers (2 greys in the Pro100 and grey and chroma optimiser in the pro 10).
*I still have 3-4 of each and go through photo magenta and cyan like it is leaking the stuff!
The 10s may print faster (no real issue), but it prints on my favourite fine art matt papers and is archival.
An A2 would have been nice, but realistically A3+ is as big as I would print myself and where would I fit it?
