I have been reading some post on this and I am new at this so if I sound like I don't know what I am doing then it is probably true. I am reading about bonjour and I think that could be a fix but the HP OfficeJet V40 is not supported by mac therefore I cannot load it on the mac side to share. I have this set up for my wife and she really needs to be able to print by tomorrow. Do I need to purchase a new printer to make bonjour work? BTW I am haviing the same problems I think as everyone else. I can load the drivers and the printer will be recognized throught the usb but then after set up the machine cannot be recognized and it will not print. If I am missing somthing simple please let me know. Thank you in advance for you help.
