If it’s a word doc that you are trying to print and if you are seeing some garbled characters on the print, check in the Print Preview screen if these characters or symbols are visible.
If visible, you need to disable the option in your Microsoft word. If not visible, then uninstall your Office package and reinstall it. If the issue persists, then try to update the printer driver. Check if your printer has to be updated to the latest version of the driver and if so, do it and try printing.
If this did not help, then try to update an alternate driver for your printer and check if the issue is resolved.
I would also suggest printing another file of the same program or a file from another program to see if the issue is with the application or the printer.
Let me know after trying these so that can help you further.
