did you try changing the print? like, does it always show that even if you change it to something else?does it work if you disable all of your other add-ons?
Try changing the print (it wont work) then close blockland and post console.log.
Try disabling Event_Print_Events and Event_Print and say if that fixes it.
Print_Events I've never heard of
Get rid of Tool_Fill_Printer and see if that helps.
