@thiagoelg Facing the exact same issue myself, tried to change type/data, recompiled the .node myself, but it seems that's it's breaking when calling the print_helper func in the lib (which is pretty reasonable considering the error is from node_printer_win.cc:735)

Also tried to switch different node versions, didn't make much of a difference, the error is the same as mentioned above.

Has anyone been able to fix this, or found a workaround?
