/**
 * A Printer Card is has two main components: the printer portion and the print job portion, the latter being paired in
 * the UI when a print job is paired a printer in-cluster.
 *
 * NOTE: For most labels, a fixed height with vertical alignment is used to make layouts more deterministic (like the
 * fixed-size textboxes used in original mock-ups). This is also a stand-in for CSS's 'line-height' property. Denoted
 * with '// FIXED-LINE-HEIGHT:'.
