I have a HP Business Inkjet 2800 (no attachments or upgrades) and it works fine on Windows through Bootcamp, but is painfully slow on Mac OS X (10.5.3.) I've always had a problem with Macs and HP printers, but this has become ridiculous. I have the latest drivers installed, but it can take over 14 hours to begin printing a single image, only about 15-30 minutes for text only. I don't print anything with more than 1 image from OS X anymore. I can't find anything that works. I even tried using a shorter (4 ft.) USB cable. Any ideas? Thanks in advance!
