Definition: Unless otherwise specified, postage can be paid for documents printed on paper or other printed matter, such as words and pictures, which are used for reading and have no dissemination nature. In addition, first, the clerk at the postal window will judge whether the letter is printed by whether it is sealed or not. Their argument is that if it is printed, it should not be sealed with glue, tape, etc. If allowed, it can be included in printed matter. In addition, if it is printed, they will not allow you to send it within a limited time. Second, the service staff will ask you with a cold tone and strange eyes: "What's in this? If your answer is a teacher's recommendation letter or an application form from the medical insurance bureau, it looks like printed matter, but in fact, he will let you send it by "surface mail", otherwise you can send the printed matter unopened, and it will be out of luck. Third, the most uncontroversial thing is that the bulk mailer only needs to see you holding a stack of letters that look similar, and then you reply to the leaflets and notices, and he will say nothing, and then calculate the price of your printed matter after weighing. In fact, they also turn a blind eye.
The opinion expressed by Longyou is correct.
The answer is simpler. Printed matter is written content with only names and no other personal handwriting. Envelopes are not included, of course, but printed matter must not be sealed by the agent for random inspection (printed matter can be opened for inspection according to regulations).
Printing, copying and other papers are counted as printed matter. Valuable "coupons, tickets, accommodation and catering vouchers" are not counted. Mark "printed matter" next to the stamp. Envelopes can be handwritten.
1. Do not seal any mail with staples. 2. Printed matter can be registered in a limited time. The definition of "printed matter" has the most important one; Is that content can't be given to specific people. For example, the meeting notice can start with "member" instead of "Ali" member.
