Any RS232 port will withsand the TTL signals on a Centronics port. If it

However, the Centroics Printer (or at least the input buffers on its
interface) are not going to like having 12V RS23 signals shoved into them.
I suspect the printer will emit the magic smoke, not the RS232 buffers

I know that the 1488/1489 combo was popular, but
the lead engineer on
the comms project at the time that I was involved insisted that the
75150/75154 combination was much superior. I don't recall what his
reasoning was, but we didn't run into any popped 7515x parts that I can
remember.
How well did those withstand a "centronics" parallel printer being plugged
into the serial port (with a gender changer?)?
