Why not just call int 17h, function 02h?  This returns the printer status.
Call with DX=printer number (0=LPT1, etc)
Returns in AH:  bit 7:  printer not busy
		bit 6:  acknowledge
		bit 5:  out of paper
		bit 4:  printer selected
		bit 3:  I/O error
		bit 2:  unused
		bit 1:  unused
		bit 0:  timed-out
These are the meanings when the bits are set.
I don't know what happens if your printer is hooked up to your serial port;
perhaps you could then use the int 14h functions to check its status.
