For some printers, with some setups, the Print command (File menu) can be very slow.
Sometimes it is so slow that it is unusable.
For example, when printing to the Epson 2000P in landscape orientation, the processing
performed by The Panorama Factory is too slow to be usable.
Workaround
Save the image to a file using the Save current image command (File menu). Then
open the image with your favorite image processing program and print it there.
