The prints are made by a local company with an extraordinarily sensitive scanner & 12-colour pigment ink printer.  They do only art prints of very high quality.  They can print on archival papers and on canvas, and up to about 1.5 metres or about 6 feet wide, so producing for example 1.5 by 2 metres (or about 6 by 8 feet).  The prints currently in my studio are on 100% rag paper and about A3 size, but other sizes can be ordered.  Price depends on size and whether on 100% rag paper or on canvas, which can be stretched and ready to hang.
