Vlite worked flawlessly. However, I inadvertently left behind my printer driver. How do I extract that from the original installation disc? Doing another Vlite session is really time consuming

Unfortunately, the HP Laserjet 1015 has no available driver for vista at HP website

Use 7zip. it can open the install.wim or winmount, imagex(a bit difficult)

and go to \Windows\System32\DriverStore\FileRepository and extract folders with prn in front of them , a lot of them ,dont know which suits your printer , that is it~~
