Hello Gregory,

Registration is not going to work for this printer for 2 reasons - she may have previously registered it, and even if she didn't it wouldn't be accepted because this is quite an old model that is no longer supported, there is no warranty for it, and so there is no benefit to registering.

As for the printing issues, there are several other concerns there, are you sure you're on windows 7 and not updated to windows 10?

For the windows 7, you need to use this driver:
