My best advice is not very good, and it is to just experiment and keep your fingers crossed. Q. I would like to use a different font than what the form automatically uses. You can, but it is not recommended. The font may have a different size, and may distort other parts of the form. In addition, keep in mind that if the forms are federal agency forms, the font was selected by the creator to make the form replicate the original hard-copy forms.
Some agencies are extremely picky about font size.
If you want to try anyway, change the font like you normally would. If the program tells you that the field is protected, go to the menu bar and select Tools, then Protection. Most times a password is not needed, so you can put anything in as the password. If there is in fact a password, you have to find it out from the forms creator, or consult the Instructions for that particular package. I think there is an error in the form itself, but when I try to change it, I am told that the form is write-protected.
