How to enable Printer pooling,print Priority,spooling

Printer Pooling: 

If you have more than one printer of same manufacturer & same model then you can enable
printer pooling. If you are pooling in printers than make sure that your all printer should be kept in the same
location or else you will not able to find that which printer has printed out you document.

Enable Printer Pooling

Go to Printer Properties –> Ports –> Check on Enable Printer Pooling –> Check both Printer Port –> Ok

Priority: 

If there is long waiting queue for print job & want to set priority to any user then you can configure
Printer priory. As soon as printer will finish the current job it will take high priority printing job at 2nd instance.

Enable Printer Priority

Install a printer twice –> Go to printer properties –> Advanced –> Set priority

Spooling: (Simultaneous Peripheral Operations On-Line)

the overlapping of low-speed operations with normal processing. Spooling originated with mainframes in order to optimize slow operations such as reading cards and printing. Card input was read onto disk and printer output was stored on disk. In that way, the business data processing was performed at high speed, receiving input from disk and sending output to disk. Subsequently, spooling is used to buffer data for the printer as well as remote batch terminals
