Hello, I'm relatively new to Mac (purchased my first desktop a year ago) and now have invested into a laptop for university. I have NO idea how networking works (I know it exists, I know vaguely of its benefits). What I want to do is to link my Mac desktop and my MacBook together. First off, there is a printer on the desktop that I'd like to have wireless access to through the MacBook. I thought I could handle that with Printer Sharing but when I try to print something off of the laptop, it endlessly searches for the printer in vain. Also, I'd like the iCals of the two computers to sync - is that possible? More over, can iTunes sync as well? File sharing in itself is not essential to me. It'd be nice but the most important things are the printer and the calendars. I'd appreciate any tips or nods in the right direction. Thanks!
