Re: serial to usb adaptor?

Anyone know of a adaptor that will allow a RS232 device (uses a 25 pin plug
but can convert that to 9 pin) to send data to a USB printer.

Nope, its not that simple:

The device has settings via a dip switch to change:
baud rate
Stop bits
data bits (even/odd)
Printer/PC bit
etc

It is NOT a PC device. It is connected to a burglar alarm and will allow me to
print out the set up and error logs. It should be connected to a serial
printer but these are now getting quite hard to find cheaply.
So this means that the adaptor must work without the use of a device driver.
I'm hoping I can just connect any USB printer and it will do a basic printout.

Can anyone help with this?

My only other option (if it would work) is to connect the RS232 port to a 9
pin serial port of a laptop and use Hyperlink or minicom to mimic a printer
and capture the output and then print it off if needed.
I think that's a much better solution anyway. It's likely to be easier to
connect a laptop for a few minutes, rather then move a printer. And second,
you might be ablt to use that computer to setup the alarm, if it allows
that.
