![]() ![]() In a nutshell, the connection between the computer and the printer has failed somehow. Why do print jobs get stuck with the status “Spooling?” The connection between the computer and the printer has failed somehow. CUPS uses the Internet Printing Protocol (IPP) to manage print jobs and queues.ĬUPS is often what’s used for printer spooling on macOS and Linux systems. One of the most used outside of Windows is the Common UNIX Printing System (CUPS) which lets a computer act as a print server and does the print spooling and scheduling. You’ll commonly come across print spoolers with Windows systems but there are alternatives. Computer speed stores the jobs in the queue, and printer speed takes over when a document has left the queue and is now printing. The reason for this is that printers don’t have anywhere near as much memory as computers, and need an intermediary program to conduct and wave the print jobs to home plate. Printer status spooling essentially means another document is printing, and yours is waiting for its place in the queue. And it’s how the printer retrieves the print jobs. It’s the computer’s way of letting the printer know there’s another job in the queue. This means you don’t have to wait for a previous job to finish printing before you select print. But it holds it in the queue until the current job has been printed in full. What this means is that the print spooler allows you to send a document to the printer while another one is printing. You can’t have two players on a base, and printers can’t print multiple documents at once. They will hold up a document if there’s another job ahead of it currently printing. I know right, printers and baseball, could I make this more exciting? The print spooler service tells the documents when they’re up next, i.e. If I may have a little fun, think of print spoolers like third base coaches in baseball. There are all different types of spoolers in computing (once upon a time there were literal tape spools running inside computers), so the print spooler, you guessed it, takes care of just your print documents. When you select print, your program talks to the print spooler service to work out how to render (or draw) your print job so the printer will understand it and put the colors in the right spots on the page. The print spooler is a dedicated program/software that essentially manages the order of the documents to proceed to the print queue. Think of print spoolers like third base coaches in baseball… What is a print spooler? The word print appeared in this introduction eight times. You then ask yourself, “What the heck does ‘Printer spooling but not printing’ mean?” Probably shortly followed by quoting Office Space. The print queue shows your stuck job with a status of either “Printing” or “Paused - Spooling”. ![]() You walk back to your computer and check the status of the print job. ![]() You’ve hit print, but you arrive at the printer to see no printout. ![]()
