I have a big issue with my printer sharing over the LAN. I think that I didnt setup the LAN correctly, so my printer is not shared over it. On the other computer I can see the printer and see the files, but I can not print anything or copy those files. This is considerably puzzling me for some days. I need to setup my network correctly.
What you must do is to allow the printer to be shared over the network. If this is done correctly, the printer will be assigned as network printer. After this you can print-out stuff on the other computers in network. Also, you must set you local hard drive to be shared over the LAN network. With that setting, your hard drive can be browsed and the files can be copied.
