(I hope this is the appropriate place to post this question.) At home, I've got 6 Windows machines (a mixture of Windows 7 and Vista) connected in a simple peer-to-peer network. A workgroup, in Windows' terms. We've got a network printer, an HP OfficeJet Pro L7555 printer, which is shared out via our router. So, no Windows machine is sharing it out. For some reason the only machine which can reliably print to that printer is mine, which is running Windows 7 Ulitmate. None of the other PCs seem able to find the printer, or they all see it as being "off line" or something like that. Mine machine is the only Windows 7 Ultimate machine, the others are either Windows 7 Home Premium or Vista Home Premium machines, however I doubt that has anything to do with it.
Why is it that the other machines can't find that printer or print to it, even though it's being shared out by our router? Our router is a Netgear N600 Wireless Dual Band gigabit router WNDR3700.
