Hi, This is an old HP model, HP PSC1350 with printer and scanner. My purpose is to do a small windows 7 as small as possible, so with none of functionality I don't need (wlan, vpn, ....). BUT the only component that don't work is the printer one. So this is what I remove : - ACCESSORIES : Windows Fax and Scanner - SERVICES : Fax, Internet Connection Sharing (ICS), Server, Workstation And this is what I keep and seems to be in touch with printer functionality : - DRIVERS : Printers (HP) and Scanners (HP) - MULTIMEDIA : Windows Acquisition Wizard - SERVICES : Print Spooler, Windows Image Acquisition And my 2 Questions are : - Do I have to check the default features "Print and Document Services", with all or none components ? - Do I have to keep "File and Printer Sharing" with dependencies (DNS, Internet Connection Sharing, Network List Service, TCP/IP Net Bios, Windows Connect Now, Windows Firewall) ? Many Thanks.
