If a printer is already printing a document, it can not print another document until the printing of the first document has finished. Therefore, the second document must form a (print) queue and wait its turn.
Print queue is when a list of documents or files have been sent to a printer for printing and they are waiting to be printed.

You need to restart the print spooler.
enqueue is a command in Unix-based operating systems that adds a print job to the CUPS (Common Unix Printing System) print queue. It is used to send a file to be printed, defining specific printing options and the destination printer. The enqueued print job will wait in the print queue until processed.
To clear the print queue of another computer on the network with a shared printer, you can use the "Print Management" administrative tool in Windows. This tool allows you to manage printers and print servers on the network. You can connect to the remote print server, view the print queue, and clear any stuck print jobs. Alternatively, you can also use the "Remote Desktop" feature to access the other computer directly and manage the print queue from there.

This is really dependent how your queue is implemented. Unfortunately, working from the outside of a queue, this is usually impossible without removing all elements from the queue. while !queue.isEmpty() print queue.dequeue()

To view the number of items in the print queue on a Windows 7 computer, click on the "Start" button, then select "Devices and Printers." Find your printer in the list, right-click on it, and choose "See what's printing." A window will open displaying the print queue, showing how many documents are waiting to print.

Return. Delete Rear---- DQDELETE_REAR(QUEUE, REAR, FRONT, ITEM) 1. [check for queue underflow] If REAR<0, Then: Print: "Queue is empty", and Return. 2. ITEM = QUEUE[REAR]. 3. Set REAR = REAR - 1. 4.Return.
A printer driver is a bit of software that instructs a printer how to work. Without such a driver, the printer may not work, or print rubbish. A print queue forms when a print job is sent to the printer that is already printing. Once the first print job has been completed, the second print job is then printed.
