Print job is 'delayed'
Sometimes print jobs are delayed due to the size or format of the documents, or there is a high volume of print jobs in the global printing queue. General printing tips are available, which may help if your document fails or takes a long time to print. Most importantly, the file size should be under 250MB.
If you have released your job on a printer and the blue lights are flashing, the job is still being sent to the printer - this can take upwards of 10 minutes for very large files.
If you have released your job on a printer and the white light is flashing, the job is being processed by the printer and is in the process of being printed.
