2. The installation software of Superstar 4.0. This conversion method is not applicable to versions before 3.9 and the latest version. In fact, the frequent update of the version is only to limit the reading, printing and dissemination of books, which is really disgusting, but now this problem has been completely solved, you must not update the reader.
Then download your e-book, open it with Superstar 4.0 after downloading, right-click Print after opening the e-book, select the printer Adobe in the pop-up window, and check the page number of the original book in the folder. If it exceeds 300 pages, choose to print the page number of 1-400. If there are more pages, it will not be printed, and if there are fewer pages, it will not be printed completely. Another reminder is that when you open the first page of a book, it always displays the table of contents page or the text page. Return a few pages to the cover page and start printing from the current page. No matter how many pages there are. Save it as a name and you can print it. After a minute or two, the PDF file came out. There is another possible problem. After printing the basic book, the printer suddenly stops printing at a certain page number (usually there is something wrong with a certain page of the book, such as missing or the page itself can't be opened, so it will stop printing). At this point, the superstar reader will be closed and reopened to continue printing, and printing will continue from the stopped page. After that, the two PDFs will be integrated.
