Data cannot be printed properly when the computer has only a small amount of free space available on the hard disk.

This condition occurs more easily when printing is canceled frequently.
When data is printed, a temporary file is created in /tmp. However, if printing is canceled before completion, the temporary file sometimes remains without being deleted.
Since the disk space becomes used up as the number of temporary files increases, use the rm command to delete files that begin with bjtmp and ciftmp.
