These may be stupid questions...
1) Are the printers you can't see shared?
2) Are the printers that you can't see network printers, or are they attached directly to another PC?
2) If they are shared, does your local Win7 account have permission to access them?
3) Have you tried going to Control Panel>>Hardware and Sound>>Devices and Printers>>Add a Printer and browsing to the printer? Can you see it there?
3) If the printer is networked, can you browse to it by IP address?
4) If the printer is shared through another PC, can you browse to other files on that PC by going to Start and typing \\computername in the search box?
Answering these questions will help me to help you.
