FAQ

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, ciftmp, or ijui.

Sometimes after a job is canceled, the next job cannot be printed properly.

The recovery procedure is described below:

1. Delete all jobs.

2. Then execute one of the following:

Turn off the machine, and then turn it back on again.

Disconnect the USB cable and then connect the cable again.

Reboot the system.

A job was canceled, but the printer did not eject the sheet that was being printed.

Execute one of the following:

Turn off the machine, and then turn it back on again.

Disconnect the USB cable and then connect the cable again.

Reboot the system.

Printing does not start.

Check whether the machine is properly connected to a computer or a network device and is ready to print.

For Fedora 10/openSUSE 11.1

# /etc/init.d/cups restart

For Ubuntu 8.10

$ sudo /etc/init.d/cups restart

When a large image is printed from an application, it may take a few minutes for printing to start.

Either wait patiently, or print the image from a terminal software instead.

Printing is interrupted if the CUPS printer settings are changed while data is printed.

If you use the CUPS Web interface or the lpadmin command to change the CUPS printer setting while the machine is printing, the print job is forcibly canceled and printing is interrupted.
This action is a result of the CUPS specifications.

If the above condition occurs, perform the procedure below:

1. Delete all jobs.

2. Turn off the machine, and then turn it back on again.

3. Stop and then start the printer by the the CUPS Web interface.

Sometimes I cannot print a document at the specified size.

The other application may overwrite the driver settings with its print setting save function.

You may be able to solve this problem by opening .cups/lpoptions or .lpoptions located on the user's home directory with an editor and deleting the corresponding section.

When I register the printer with the lpadmin command, the default paper size is set to Letter.

Perform the following settings:

For Fedora 10/openSUSE 11.1

1. Delete the printer from the spooler.

# /usr/sbin/lpadmin -x [printer_name]

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.

For a USB connection

# /usr/sbin/lpadmin -p [printer_name] -m [PPD_filename] -v cnijusb:/[USB_port] -E

For a LAN connection

# /usr/sbin/lpadmin -p [printer_name] -m [PPD_filename] -v cnijnet:/[MAC_address] -E

For Ubuntu 8.10

1. Delete the printer from the spooler.

$ sudo /usr/sbin/lpadmin -x [printer_name]

2. Open /etc/papersize with an editor and replace the paper size with the size that you want to set as the default.

Example: "Letter" -> "a4"

3. Restart CUPS.

$ sudo /etc/init.d/cups restart

4. Register the printer to the spooler again.

For a USB connection

$ sudo /usr/sbin/lpadmin -p [printer_name] -m [PPD_filename] -v cnijusb:/[USB_port] -E

For a LAN connection

$ sudo /usr/sbin/lpadmin -p [printer_name] -m [PPD_filename] -v cnijnet:/[MAC_address] -E

In Fedora 10, the start of printing may be delayed.

When a large image is printed from an application, it may take a few minutes for printing to start.

Either wait patiently, or print the image from a terminal software instead.

The printer does not print when several drivers are installed.

The printer may not operate in a USB connection if several different version of drivers are installed.

Perform the operation described below.

For Fedora 10/openSUSE 11.1

1. Re-register the non-operating printer according to the instructions for this version.

# /usr/sbin/lpadmin -p [printer_name] -m [PPD_filename] -v cnijusb:/dev/usb/lp0 -E

2. Restart CUPS.

# /etc/init.d/cups restart

For Ubuntu 8.10

1. Re-register the non-operating printer according to the instructions for this version.

$ sudo /usr/sbin/lpadmin -p [printer_name] -m [PPD_filename] -v cnijusb:/dev/usb/lp0 -E

2. Restart CUPS.

$ sudo /etc/init.d/cups restart

With Ubuntu 8.10, you may not be able to print large images from application.
