Some printers do wait for the queue to clear and require a manual form feed to clear, although putting out a formfeed character will do the same thing, usually. Are you sure that ff is getting out? We had trouble at one point with something eating it. Also check your printer's manual, it may have a special procedure for emptying the queue. The older Panasonic manuals are mini-programming manuals, IIRC. You might try polled mode printing too; irq 7 is the junk IRQ and something may be making it stick up.
