Printing with PrintImageFileWH Action Command

Hi all, I am using the "PrintImageFileWH" action command but am finding that it's not printing more than one images in a row, it prints one then stops printing. After resetting the printer by on and off it prints the next image. I'm having to basically reset the printer after a print. Is there a command to reset the printer after a print? Maybe this will help resolve my issue. Any helpful suggestions always appreciated. The command I am using is: "PrintImageFileWH "[TempFolder]Printout.jpg" "6.1466666666666665" "2.066666666666667". It is an image file 1844x620 pixels and converted to inches as needed. I notice that when the printer comes back it prints a tiny line of the previous image and eventually prints the next image file.
