imac, hp printer and airport express

hi,

can you plese help me, I want to print wireless. I have conect printer to router via usb, instal driver for printer to imac, select in airport utility to wireless printing, add a new printer which was detected in (sistem preferences, printer and fax,) but doesnt print wireless.
What must I do more?
Regards.

Have you tried connecting the printer direct to your iMac via USB, get it working that way first, and then setup the wireless connection? I don't understand why you have connected the printer to the router?

It would also help if you listed the model of your printer and some with a fax use an ethernet connection for networking.

I have connected the printer (hp color laserjet 1025) directly to the imac and it prints normaly but I would like to have wireless printing.

Ok according to that model no. you have the ability to use the internal bg/n wireless,
USB or 10/100 ethernet if you hook up the ethernet to your router everyone in your LAN should see and be able to use it. If you use the internal wi-fi same thing should happen but with a shorter range if set up correctly. I would only use the USB for initial hook up to the Mac then after all the drivers are updated along with any firmware then choose which wireless fits your needs. Personally I will use ethernet when available.
