As the title indicates. After acquiring more radios from Tonglian, manually writing out a large number of QSL cards becomes very time-consuming and laborious. Even when using a printer to print addresses on A4 paper and then cutting and pasting them onto envelopes, it still takes a lot of effort. Therefore, I would like to ask fellow operators how to directly use a printer to print information on QSL cards and print addresses on envelopes. Is there a specific type of printer required? Are there any convenient programs for exporting logs or addresses?
