I have to print 4 copies of my final draft phd thesis (400 pages each time), then there'll be another 4 copies when I submit and then another 6 or so when it's accepted. I'm an Arts candidate so there are lots of colored artists' images. I've costed sending it out to profesional printers but it'll be cheaper to get a printer myself. I need speed and good quality images (my hp officejet 6110 all in one does acceptable quality but is too slow for this quantity). Can ayone advise me what to buy? I'm considering the HP Officejet Pro K550. Thanks!
