Win 7 Printing

Odd thing has been happening.   I sent documents to print through the home network, at numerous times yesterday, and all was OK.   When  I went to print today, nothing happens.  Checked all settings and everything OK.  Printer que says files are there, but won't print.  Then out of the blue a few hours later the prints started coming out of the printer.

This is bazzar.  This has happened a few times this week.

Any suggestions?
