Oh dear, idly scanning through networking section looking for 0 answers topics, I noticed yours. Very belated welcome to Forum, where you can find an overwhelming amount of information. You no doubt know already. I think from the date stamp it looks like your question feel on the cracks of the floorboards so I will lift your topic a bit.
Networking is probably not the best section for printing related problems, and having the wireless connection may be part of the problem so could belong here.
A very likely reason for nobody jumping in to give answers, there is not many facts
1.. Have you tried to connect directly with a network cable? Then see if you can print?
2.. The model of your printer, if somebody has the same model you may get a response from the owner?
3.. How experienced a computer user are you? This can help members assessing what degree of help you may need
