Printer worked and now it says offline.
I just got a macbook pro in August running lion... There was a deal to get a printer as well so I got it. The printer is a hp photosmart D110 series..it is connected to my computer through wifi. It was working really well for the first little while but now (after not making any changes to my computer) the computer cannot find the printer. the message i get on the printer page is.. "printer not connected" and "printer offline". On the printer it says that the wifi connection is good. I have no idea what to do, please help asap. I need to print for school.
