About printing from hp officejet pro 8000

Hi,
I am Diwyesh Dave. I am using HP officejet pro 8000 printer in my project. I have written a "printer driver program" in C language for my project. It is a USB printer, and after sending the data, I dispatched the USB.

SCENARIO: When I send some data to print, it prints whole data successfully, but after printing the whole data, it wait for more data to print and shows the message "WAITING...".

QUERY: So my question is that what command or set of characters need to be sent to printer to disable it after printing the data.

Thank you

Below is the list of command used by PCL5 compliant hp printers ..i think u will have to use JOB STOP command .
How are u communicating with printer through PC or microcontroller .I am using PIC32 mx and porting microchip application library demo program with HP printer deskget 2010 i have been able to communicate and get descriptors , but unable to print anything .
