Have a need to hide the toolbar yet still need to crop an image. Is there a keyboard command that would allow me to crop with the toolbar minimized? Guidance sought

New to networking and although I’ve installed printers to workstations, I’ve never installed a new printer to a server. I only know that an IP address is to be reserved for the new printer through DHCP if the printer software does not scan the network and find an unused address. If there is a simple how to with pictures I would appreciate it. This is Server 2003. Much thanks for any guidance
