What is the best large format printer? -

I am looking for something to print wall-sized maps and pictures. Image quality is important, but I am also concerned about the cost of ink and other supplies. I have about $5000 to spend, but would like to spend less if possible.

you need to look somewhere with used printers. I am using the Epson Stylus 9800 pro and it is amazing but it costs about 5 G s. Look at Epson and find the large format printers for personal use. Check this link I love these pritners but you need lots of research and studing to get the full capabilities on them.
