WL-500gE and laser printer Minolta PagePro 1300W

Hello, I am a proud owner of WL-500gP and I have problems with installation of printer Konica Minolta 1300 W on my PC. It is connected to my router and I can see it in its interface (in "Status"). I tried to install it exactly like it is stated in the Quick start guide, but it doesn't print anything. I have to say, that I am lame, so there can be something I did wrong, but there is one thing I want to ask you. I was given an information, that some routers don't communicate with cheap printers, that support only GDI. And my printer belongs to them. So should I try harder or could I stop, because this won't work ever?:)

Thanks for your advices.
