Color on printed Invoices

[blessedessentia]

Hello,

I am trying to print an invoice but the black color is not showing on the printed paper. I believe the color on the invoices are gray, but I need to change the color on my invoices to black. 

How can I change the color on my invoices?

Thank you,

Not sure that's an option for Invoices.   I believe all you can do is add a custom logo or graphic.   You can change the color scheme of the PayPal Checkout pages however, your choices are limited.   Perhaps someone else has some tips on this.
