I have been having a problem with printers hooked up to my Airport Express. With the first I just thought it was a faulty printer, but now my new LaserJet is doing it too: it won't let me print hardly any PDFs, at least through Adobe Acrobat. It'll open the printing program and process it, but then the status will just change to stopped and it won't print. If I convert the pages I need into TIFF files, Preview will print it, but as a PDF neither program will. Any ideas?
