Check copy: green = filled, yellow = handwrite (submission date, G01, any blank agent fields). Print the version without highlights, A4 at 100%. The first PDF downloads about 4 MB of forms, plus the parts of the Noto Sans JP font it needs from Google Fonts (fetched by character group; your text is not sent). Check everything before you submit; this tool is not tax advice.
