i am just using HP 8500 and I think this is most of the efficient printers of recent times. Since I was opting for an Wireless Communication , I made a choice for this one. I was at present working on Mac but it came to my notice that there were some issues as I was with some "Communication Error" on my printer. It was previously working fine but ,later printing was not possible from the Mac . it was saying something like this as “Connecting to Printer" and then gave "Communication Error". I just thought it would be OK when I connected wired. Made some factory settings made some latest firmware update but it was not solved yet. So anyone here can solve this one as i am too lazy to find some solutions on other sites and posting the same issue.
