Can't print over network

Need help!!!
I have 3 DELL XP computers through the wireless network share the printer. They work well before. #1 connect the printer and #2,#3 using wireless connecting through the route which connect the #1 to connect printer.
Recently, #2 computer was out of network (can't print) but still can get into internet.
From #2 My network places/only show #2 itself, can't see #1 and #3.
From #1, #3 network places/they can see each other and also show printer.

#2 can ping #1 and #2self but can't ping #3.
#1,#3 can't ping #2.
What's problem? What I can do now? Please give me advices, thanks so much!
