Clearly these will never be as good as, or as accurate as properly produced charts. Most home printers just don’t have the ability to produce true blacks with razor sharp edges and the paper you use is unlikely to be optimum. But, the link below takes you to a nice collection of zone plates and resolution charts that are useful for A/B comparisons. I split them up into quarters and then print each quarter on a sheet of A4 paper, joining them all back together to produce a nice large chart.
