Do I have to have a handprint for meditation?

Meditation and fingerprinting are not unique to a certain religion or behavior. They exist in various systems, such as Buddhism, Taoism, yoga, even traditional Qigong, some techniques and so on. No matter what kind of system, as long as you practice in a certain order, to a certain extent, you will involuntarily pose some postures, and then different postures handprints represent your different emotions at that time. If you accept the knowledge of handprints during this period, it will be absorbed very quickly. Handprints are not necessary. Different systems have different requirements and different periods have different requirements. Some people take off their shoes before entering the door, some people take off their shoes after entering the door, some people can change their shoes, and some people don't care at all. The result depends on the owner's habits and requirements.
