Please verify that the documents waiting to print are not stopped. When a printer encounters any problem printing a document, it just stops printing. Any document that is subsequently sent to the hp printers review cannot be printed until the previous document is completely printed.

Printers print one document at a time. This is similar to cows crossing a stream. If the first cow comes the stream and does not cross, all remaining cows wait in line to cross the stream behind the first cow. If the first cow does cross the stream, the other cows follow. When one of the other cows refuses across the stream, the cows following it stop and do not cross the stream.

Similarly, printers print all documents in the order that they are sent to the printer. If the ink runs out, if there is a paper the error, or if there is some other malfunction that stops a document from printing, that document and all remaining documents stop printing. After the error is corrected, the document may or may not automatically start printing. Sometimes you must restart the document printing for that document and subsequent documents to print.

The printer document waiting line on Windows 7® is found by clicking on the "Start" button and opening "Devices and Printers". In the "Devices and Printers" window you select the printer you are using. Clicking the right mouse button opens a pop-up menu from which you select "See what's printing". This opens the printer queue. If there are no documents listed, then Windows® believes that all documents have been sent to the printer and printed.
