PCL was originally ASCII with proprietary escape sequences mixed in, but that spec page says that printer understands PCL 6, which apparently is a stack-based graphics language like PostScript, except binary. It's supposed to include backward compatibility with PCL 5, but doesn't always. So possibly what that printer understands has nothing to do with ASCII. https://en.wikipedia.org/wiki/Printer_Command_Language I don't like it either, but there is heavy pressure to hold down the cost of printers.
