Speccy does not acknowledge Dell v313 printer

After clicking on the "Peripherals" link, the Speccy display will acknowledge the presence of my Dell 720 color printer, but does not acknowledge the presence of my Dell v313 AIO color printer. ALL driver files for both printers are current and present. Both printers were turned off at the time.

FOLLOW-UP POST: I have discovered that the Speccy software WILL acknowledge the presence of the Dell v313 AIO printer if it is turned on, but for some reason will only acknowledge the Dell 720 printer if both printers are turned off at the time I run the Speccy program.
