I am trying to resurrect an old dye sublimation printer, the Olympus P-400, to print recent JPEGs. Unfortunately, I do not have any Win2K (or older) systems on which I can install the printer driver. However, the P-400 can print JPEG images stored on a SmartMedia (obsolete) card inserted into the printer.
I have a SmartMedia card containing a few images captured by my old Olympus camera, and they print on the P-400. However, if I copy a “generic” JPEG to the SmartMedia card, the printer’s LCD interface lets me try to print it, and the printer then runs through all the motions, but no image appears on the paper.
I named the “generic” JPEG similarly to the ones that print, and I cropped it to the same size and DPI of them, but still, no image prints. I suspect the printer’s firmware is looking for some specific information in one or more of the JPEG marker segments. Both types of JPEGs (ones that print and ones that don’t) have an APP1 EXIF segment in little endian format as the first in the file.
I am in the process of writing software to dump JPEG files in order to try and determine what I might do to “generic” JPEGs to get them to print. While I am doing so, I thought I would ask:
What JPEG format do I need to save images as in order to direct-print from a memory card on the Olympus P-400 dye sublimation printer?
