Problem in wireless connection.

I hav 3 laptops with me.all connected with printer wirelessly.printer does work from 1 of the laptop but doesnt works from other 2.but when connected by a rj47 connector it does works.Internet also works properly in all of them when we give print command it printer take the page but doesnt print anything .another thing which i notice is that after givin print command document never goes fully i mean if document is of 134 kb it goes like this 128kb/134kb. some of its portion is always left somewhere.but through lan cable it goes fully and works properly. there is no problem in wireless connetion as internet is working fine.also it does give inf to printer to print. i hav reinstalled printer software,restated router ,modem printer also i restored my previous windows settings but it doesnt work. there is no problem in wireles router and modem as 1 of my laptop does everything very finely through wireless network. For the temp basis i hav connected one of my laptop with router trough lan wire and make this laptop as a print server now all the laptops are printing through print server using lan cable. please do something so that i am able to use every thing wirelessly.
