基于您的代码的 MWE 为我编译并产生了我期望的输出。

\documentclass{article}
\usepackage{amsmath, tabto, fancyhdr, graphicx, geometry, blindtext}
\geometry{a4paper,top=0.5in,left=0.50in,bottom=0.55in,right=0.50in}

\pagestyle{fancy}

\fancyhead[CO,CE]{\includegraphics[height=30pt]{example-image-a}}
\fancyfoot[LO]{PRINT NAME: FirstName LastName}
\fancyfoot[CO,CE]{SIGNATURE: \includegraphics[height=30pt]{example-image-b.png}}
\fancyfoot[RO,RE]{Date: \today}
