Printing .pdf Preview vs Adobe Reader
Running 10.7.2 and InDesign CS5.5 I created a newsletter and exported it to .pdf. On the screen, the document looks almost identical when viewed in Adobe Reader 10.1.1 (Adobe X) and Preview 5.5.1. However when I print the document (I have to send 3 hard copies to some non-email folks), the quality of the print is noticeably worse in the Preview-printed doc than the Adobe-doc. In the Preview version, the colors are less bright and the text is not as sharp. However from Preview I can print double-sided no problem. In Reader, it asks me to use my printer settings which are set to 2-sided but it doesn't print that way. I've looked for preferences in both programs to adjust color and printing and find nothing. Why would the same document print so noticeably different? My printer is a Brother MFC-9840-CDW color laser.
Sorry if I've overlooked an obvious answer and thanks in advance!
