Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I agree with the previous writer. In MS 2010 a spreadsheet selection can be copied and pasted as a picture into a Publisher file which can then be re-sized to fit. In MS 2013 the end result is fuzzy and not suitable for print.
Try this experiment. Instead of copying and pasting, and assuming you are using Excel, after you have made your spreadsheet selection, right click and Save As a picture directly from Excel. Choose a higher resolution, perhaps 300 dpi PNG file and save to your hard drive. Then in Publisher insert > Picture box and browse to where you saved the PNG and insert it. Ideally size at 100% scale or less. PNG files tend to scale better than JPG or GIF files.
