Cannot print to shared printer network

I've been looking for an answer to my problem all day and have yet to find any help.
I thought I'd figure this out before upgrading to Windows 10.
The issue: I am trying to print from my laptop computer, which is running 8.1 Pro, via wifi to a network printer.
The printer is connected by USB to my main computer which is running 7 Pro. All print and file sharing is turned on.
The printer is shown as being connected on my laptop and I can access files, pictures, etc. on the network.
But it won't print anything. It appears it is printing but nothing happens.
Another computer, also running 7 Pro, can print just fine but it is a wired connection.
I know it's probably something simple but I'm stumped.
Any help would be appreciated!

Most likely the Print Server on the Windows 7 computer is screwed up. You would be better to get a Print Server that is compatible for your printer, to place it on the network, vs using another computer as sharing.
