Print spooling file size causing print to fail

jon_eccomputers used Ask the Experts™
One of our clients is experiencing a problem with printing to a shared Epson SC-P600 printer. It goes to the the queue and spools up to around 10x the original size then fails as the printer appears to be timing out. This is happening to both .PDF and .JPEG.

So far I have tried; Restarting the devices, removing the printer and re-adding, Restarting the print spooler, removing the share then re-sharing, deleting the printer from the original source, reinstalling the drivers.

Is there anything that i am missing?

Make sure you have the most recent driver on hand.

Remove the printer (Devices and Printers).
Clear the printer spooler (not just restart it)
Right-click “Command Prompt” and select “Run as administrator“.
Type net stop spooler then press “Enter“.
Type del %systemroot%\System32\spool\printers\* /Q then press “Enter“.
Type net start spooler then press “Enter“.
The print queue on your Windows should now be cleared.

Make sure the spooler is clear (no entries in it).

Now go back to Devices and Printers, Printer Server Management, Drivers Tab. Remove (delete) the Epson driver.

Restart the computer, install the most recent driver and try printing again.
The fact that the spool file is 10x the file size is quite normal. I have often found that Win dows has trouble with very large (>500MB) spool files. What size is yours?

You say you have removed and reinstalled the printer. However, you also need to remove the driver files. In Devices & Printers, after deleting the printer, click on any other printer and then on "Print server properties" from the menu that appears. Then click the Drivers tab and remove any instances of the printer from the list. Now reinstall the printer from the CD or from a downloaded driver.

Another thing to do is to make sure that "Start printing after last page is spooled" and "Print spooled documents first" are ticked in Printer Properties.

If the spool file is excessively large, you need to check why. For example, images do not need to be larger than necessary to produce 300 dpi on the paper. The fact that the printer specs say 5760 x 1440 dpi is irrelevant for that. If an image is 10" square, it needs to be anout 3000 x 3000 pixels. Anything larger is a waste of time; less than 200dpi may mean that you see a reduction in printed quality. Reducing the image size is usually the best way to reduce spool sizes. It is however driver dependent: the driver may insist on sending the image at the printer resolution selected in the driver. In that case reducing the number of pixels will not help.
Thanks for the points, Jon.
