V515w Printing / Communication Problems

Hey everyone, I have had a Dell V515w printer since 2011. It has always seemed to communicate and print perfectly from my desktop computer (Inspiron 580). However, for the past several months it has been having some issues. I don't remember when it began, but what happens is: -I will print a few documents (usually they have to be back to back now to actually print) -Then at some point, the printer and computer stop communicating -After this, in order to get a document, I will sometimes have to restart or shut down the computer -Depending on the time frame, the printer will eventually spit out the document at some point, or I will have to turn the computer back on for it to print it Any ideas on how to fix this? Oh, and I am connected through USB and network...I have tried printing through both and have had issues with each. Thanks!
