Hi Miromy
I understand you aren't able to print over the wireless network.
I have included a document for setting up the wireless network.
Click Here.
Here is a document for troubleshooting wireless connectivity.
Print out a wireless network page.
If you have a valid ip address for the printer try and access the embedded web server.
Type the ip address into internet explorer address bar.
If it loads the printer's network page then the printer is on the network.
Run the add printer wizard.
Go to control panel, printers, then click add a printer, run through the wizard to setup the printer. Try printing now.
If you need more assistance just let me know.
