Printing...

So I've learned a lot about printing and also I knew more than I realized. When I went to help print out the new menu I designed. We had a problem with fonts, and the printer not lining up with the weird dimensions of our menu. Luckily I was able to know what I was doing...I even taught the man at Printer counter a few tricks! I felt very experienced! lol But one thing I had trouble with, but luckily I worked around, was being able to package or do a similar type function in AI. Because when I imported and even place my menu as a whole into indesign it did not save in a high quality form. it became very pixilated...does anyone know another trick??!!
