Thank you. Could you change the program that it only prints the size without text?

Based on your query, it seems that you want to print the page size without any text. Below are some possible solutions:

Change the page size: If you want to change the page size of the document and print it without any text, you can follow the steps provided by Microsoft to change the page size of a Publisher document. After changing the page size, you can print the document without any text.

Change print settings: You can also change the print settings to print only the page size without any text. For example, if you are using Microsoft Edge browser, you can follow the steps provided by Microsoft to change the print settings. Similarly, you can follow the instructions provided by HP to change the print settings in a document. Once you have changed the print settings, you can print the document without any text.

Modify document for printing: If you want to print a document without any text and only the page size, you can modify the document for printing. For example, in Microsoft PowerPoint, you can modify the Notes Master to uncheck the boxes for the text placeholders that you don't want to print. Similarly, in Microsoft Excel, PowerPoint, or Word, you can change the font size of selected text or cells to 0 to make them invisible before printing.

I hope one of these solutions helps you achieve your goal of printing the page size without any text.
