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.

Log in as root and perform the following settings:

1. Delete the printer from the spooler.

Example: If the printer is registered as PRINTER

# /usr/sbin/lpadmin -x PRINTER

2. Open /etc/cups/cupsd.conf with an editor and add the following line at the end according to the language environment.

Example: In the English environment

DefaultLanguage en_GB

3. Restart CUPS.

# /etc/init.d/cups restart

4. Register the printer to the spooler again.

Example: If you want to register the printer as PRINTER (input the PPD file name in "canonxxxxx.ppd")

# /usr/sbin/lpadmin -p PRINTER -m canonxxxxx.ppd -v cnij_usb:/dev/usb/lp0 -E
