You often need to make changes in the settings of the application you're using to print from rather than the printer directly if you want to change the size of the font while printing from your Epson ZP-4200 printer, First you need to open the file you want to print then go to the file menu and choose the print option. The words could vary depending on your operating system and program, but you should search for anything like "Page Setup" or "Print Options." Turn this option on. You should be able to change the scale, paper size, or layout in the Page Setup or Print Settings window. You can change your scale options or increase the font size here by changing the settings. Some applications provide a preview of the printed copy of the document. Use this to make sure the font size fits your requirements. After adjusting the settings you can go for printing.
