A Print Queue is a temporary storage area on a computer or printer that holds print jobs before they are processed. When multiple documents are sent to a printer, they are organized in a queue, allowing the printer to handle one job at a time. This ensures that each document is printed in the order it was received. Users can view and manage the print queue through their operating system, such as Windows or macOS. If a print job encounters an error or needs to be canceled, it can be done directly from the print queue interface, helping to streamline the printing process.
