How do you alter font size for check printing? Print set up with alignemnt doesn't help this issue.
The print setup is used to help QBO align the amount on the check, sweetchef-scalia.
Being able to customize the font used on the checks sounds awesome. I'd encourage you to send this idea to our developers. We update QuickBooks Online a lot, and there might be a chance to have this option added soon.
