^ then you best bet it this what i have done in the past for two books downloaded pdf
a> i printed them out myself in inkjet printer with desi ink refills 352 pages ink costed me about 135 rupees with medium draft quality printing at 300dpi X 300dpi (cost may be higher if you are using books with lots of picture)
b> always print odds first then evens in this ways you'll print both side of single sheet so 352 pages are actualy 126 sheets only.
c> never use regular 20 pound press computer paper available normally even though it is very high quality but its very thick so your 250 pages book would be as think as encyclopedia, instead i used local paper half the thickness of the normal paper for about 120 rupees for 400 pages rim.
d> after you have printed and collated then go to local book store and have it binded using comb binding, price varies i paid 80 rupees for that.
