I purchased an Deskjet 3520 printer 1 week ago on the uderstanding that it will automatically print 2 sides (Duplex printing) this doesnt work either from a PDF, or Adobe InDesign even though "Print both sides" is checked.
I am using a MacBook pro OS 10.8.4 I have also downloaded and installed the latest drivers.
This the first HP printer I have used, previous printers have been either Canon or Epsom, if I cannot resolve this issue I will return the printer, get a refund and switch, probably to Epsom.
