Hi Snakips
the 1.1V must be from the printer port
it would help to have photos showing all of the two sides of the PCB
if the photos are clear enough it may be possible to reverse engineer the board as I've done a few times
it looks like there is a fuse holder on the board
if a fuse has blown , I'd check for short circuits
I'd expect a switch mode regulator has been used like the LM2576S used on the this TX14175 board

PS
another board I reverse engineered to see why it didn't work as expected
another classic Chinese board with design errors
