After a trip to Japan, I got a slip stapled to my passport, the first bullet point of which reads:
"Please type or print clearly. Write by using black or blue pen."
I have already read through this question on using 下さい vs ください, but the answers emphasize using the two as differences between objects/actions, て-form/other forms, and personal preference. Here, these are both actions, both て-forms, and both written on the same sheet, so personal preference is not a factor.
Given the English translation above (provided on the same stapled slip), I speculate that it might be a politeness indicator, more of a soft request to print neatly, whereas the second request is more firm and required. (But that's just a guess of my own.)
What is the purpose for using the kanji and non-kanji forms of ください in this sentence, given that they both follow 「～で記入して」?
