Morphology
Both constituents are typographic measurement units, so the compound denotes a type of measurement in printing; a learner who knows 'pica' and 'em' will therefore infer it refers to a printing/typographic unit. The exact numeric value (1/6 inch) is specialized technical knowledge, but the overall compositional meaning is transparent from the parts.
Etymology
Pica em: The noun pica em comes from old printing shops. Printers used a small unit called a pica and the width of the letter 'M' called an em, so a pica em is a size based on that letter and is used to measure line length and space.
