I am helping a friend set up their new computer, an HP HPE with Core i7 running Windows 8. I have installed and shared an HP LaserJet 1018 printer on the Windows 8 machine. A second computer is a laptop running Windows Vista. Both computers are connected through a wireless router.

When installing the printer on the Vista laptop, I'm asked to enter login credentials for the Windows 8 machine. I do so being sure to check the box that says remember this password (or something similar to that). Then the installation proceeds without any problem. At the end I'm able to successfully send a test print to the printer. After this I can open other applications and print anything I want.

However as soon as I reboot the laptop, access is denied and I'm no longer able to print anything from any where. Any ideas? Thanks in advance for your help!
