Verifying Printer Communication
Check whether the printer cable is connected.
If it is connected, check whether it is properly plugged in to the end, loosened, or coming off. Because this phenomenon may also be caused by a contact failure, unplug the cable, and then plug it in again.
If you are using a USB hub, connect the printer directly to the computer and check the connection.

Check the message displayed on the [LCD Monitor] of the printer.
Deleting documents in the print queue
If you are printing from a PC, and printing stops halfway or is not completed for some reasons, printing data may remain on the PC as a document in the print queue.
If there are documents in the print queue on a PC, you cannot print out new documents. In this case, delete documents in the print queue, and then try to print again.
Setting a Default Printer (Windows)
If you also use a printer other than SELPHY, this other printer may be set as a priority printer.
Set a printer commonly used as a default printer by clicking [Set as Default Printer], and then try to print again.
