It varies depending on content (yours is mostly black and white, 190 pages, colour cover with some colour pages, right?) and the size of the print run, AND what type of printing you choose.
Black and white is cheaper than full colour - but yours will be more expensive per copy as there are colour-pages. Then there's the difference between digital print and off-set printing, and what type of paper you use.
I had a run of 50 copies of a fully black and white comic with colour-covers, about 200 pages long, printed a couple of years back at a local Swedish printer, and it cost me about 5.5$ per book. The price was due to the choice of paper, the colour cover, the length of the book - but mostly my small print-run. Larger print-runs cost less per book - but on the other hand, the total price is higher because you order more books.
The best way to go about it is to contact printers and ask for a quote. Check out Ka-blam, too, especially if you're thinking of doing a small print-run.
