Up until a few days ago I could print from my computer OS windows 7 to an old HP laserjet 5 printer connected to another computer in our small network. I recall some menu tab that had something to do with my router and either my computer or the printer. Reflecting back perhaps I screwed up and selected mistakenly a menu option. This offline status has sometimes been able to change by going thru a process of selecting menu options (tabs) and going from offline to online but cannot find that menu option. How do I get that menu option back into the mix????
