This is probably the quickest bookmark print ever. Print one of these, put on an elastic band and you're set.

Put it on the page you're at and place the arrow on the current row. Easy as that.

I printed mine with 0.12mm layer height in PLA. If you need support for this you'll probably need to check your printer. ;)
