Hi glenrae57.
Welcome to the Microsoft Community.
Your printer will automatically print A5 vertical layout content. I sympathize with your experience of both parties shirking responsibility. I will try my best to help you solve the problem. First of all, I would like to know what method you use to print what content? For example, print pictures through the right-click menu or print documents through Microsoft Office? Knowing these contents is very helpful to understand your problem.
Before understanding this information, you can try to modify the default settings of the printer:
- Press "win + i" to open the settings, and go to "Bluetooth and other devices"-"Printers and Scanners" in turn.
- Turn off the "Let Windows manage the default printer" option.
- Then select the default printer yourself. In the same interface, click "Set as default" to the right of the printer you use. Make sure "Default" appears under the printer
- Click the printer just set as default and select "Printer Preferences"
- Set the printing properties of the default printer, set the printing direction to the direction you want, and set the paper to A4, save the settings and exit.
If there is no problem with the printer hardware, you can print to A4 when printing with the default parameters.
