Homegroup computer not allowing access to printers or files

I have been spending the whole night trying to reconfigure my win7 desktop to allow me to connect to shared files and print with the printer, both of my computers are windows 7 and in a homegroup, I have made sure all the correct services are running., Windows troubleshooting does not solve the problem as usual! I have not printed in a while, so I decided to go in and try to connect to the printer, and the printer is showing as offline. I try to install a new printer since homegroup says a new printer was found, but this does not work, I try to access shared libraries on the computer with the printer and keep getting the error. This account is not allowed to access this shared resource. I have it set up to allow sharing without passwords, and I have shared between these computers before, something is messed up and i can't find what it is. I tried restarting and going through all the homegroup options one by one, firewall, etc... anybody solve this problem recently? thanks

Here is the thing, this is not working, when I go to the homegroup page, it says that a homegroup printer was found but when i click to install it, nothing happens. I think that something is blocking my ability to connect to any of the shared libraries or printer. On the other computer(B) I am able to access the files on this computer(A). Printer on (B) works on B but shows as offline from A. I cannot access any of the files on (B) because it says that there are no other people in the homegroup, but the other computer(B) is in the same homegroup, and on that computer(B) I can see and access everything on this computer(A). I have tried what you said, it is a home network. I have done this several times on both computers, There is no password on the (B) computer, but there is one on this computer(A). This issue is still present.
