LaserWriter IIf and IIg: All Ports Active vs QMS ESP



Is Apple's "all ports active" the same as QMS's ESP?

Both Apple's "all ports active" and ESP allow connecting the printer's
different ports at the same time. ESP goes the extra step of guessing what
language is spoken (PCL or PostScript) and switching to that mode. "All
ports active" allows reliable job switching in software.
