The status display does not change until printing starts.
Also, if an error is indicated by an LED on the printer, eliminate the cause of that error.

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. When a large image is printed, this temporary file also becomes large.
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 and ijps.

A print error occurs after the job hold operation is executed.

The cause of the problem is that the Linux USB driver is not equipped with a device reset and cannot execute printer reset.

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

Disconnect the USB cable and then connect the cable again.

Reboot the system.
