After all of your print jobs are finished, spool (.spl) and temporary (.tmp) files may remain in the Windows\Spool\Printers or Windows\Temp folders.
To work around this issue, manually delete the .spl or .tmp files from the Windows\Spool\Printers or Windows\Temp folders.
By default, spool (.spl) and temporary (.tmp) files are automatically deleted after all of your print jobs finish unless the logical printersettings state otherwise. Spool files are the actual spool (print job) files. Temporary files are usually associated with LPR print jobs.
