You can now use that drive just like any drive on your Windows machine. Even if you shut your system down, the next time you start the system the drive icon will still be there. The first time you try to use the drive you'll be asked for your password. It is also possible to see the resources available on the UNIX systems in the Network Neightborhood . An old version of this page explains this is painful detail.
Printing is a little more complicated.
You can not, at the momemt, access any of the color printers. To use the printers, the first thing you have to do is connect the printers with a printer driver. I would suggest only doing this for the printers you are going to use. Generally, you'll only need to define the driver for the ps printer, which is our generic postscript queue. Define the others only if you find you need them and are certain you can actually use the printer - some of the listed printers are physically inaccessible to most users.
