Hi Joe,
I just did a quick search and found that the BP-1600 uses EPP (Enhanced
Parallel Port) protocol on the parallel port rather than using the port
like a GPIO port. Since this is a higher-level bidirectional protocol,
it should be easier to find a USB converter that will work. Look for

My impression is that old software that make their own timings
and devices depend on those timings may have issues due to the
fact that there is a delay from write to LPT to bits really appearing on

Yes, USB to LPT adapters are a comodity item, although I suspect they
are getting a bit of old stuff we no longer carry these days.

Joe,
It just so happen I have a never used USB-printer port adapter (with the
Centronics connector). There is no driver for it, I believe the driver comes
with Windows.
You are welcome to it.

Dear Joe,
Be aware, the parallel printer ports are not a substitute for the LPT port!
My experience is that only two things work:
1. A PCI card in your PC to add a LPT port (cost around 15 Euro)
2. Homebrew LPT ports. If my memory serves me well there was a design in
the June or July/August

As mentioned the real answer is no unfortunately. I used to use raw printer
bits for all kinds of stuff. Not anymore.

Hi Joe
As per other replies I was going to suggest this won't work because USB
adapters are for printing only and my solution would be to buy an old 486 or
early pentium laptop and use that, I've bought several over the past few
years for really silly money on Ebay for this very reason,

only support printers. Scanners, software key dongles and other

Those should be real ports. They probably connect through the PCI buss
as a PCMCIA card would.
For those looking to PCMCIA/Card Bus, be careful. There ARE cheap cards
that connect through USB rather than PCI. The true PCI cards DO work.

Yes it exists, and does exactly what you want:
your applications see a 'real' LPT port that you
can write/read at low level like it was a real hardware port.
It has a DB25 connector on the end.
I have two of them, they work great.
I tried old prom programmers and lots of small PLL loaders etc
My solution was similar. I have a few old systems that work fine and
have serial and parallel ports. For my more recent workstations, I
add a PCI or PCIe serial/parallel port adapter if needed.

A couple of years ago I bought an Intel Atom Dual Core board. It's
equipped with 2 com ports and 1 LPT port. A quick check at Newegg.com
shows that most, but not all, Atom boards (regardless of brand) still
include one or two COM ports and 1 LPT port. So, for somewhere around
$100 or less
Hi
I think the answer to the Atom puzzle is that the standard Southbridge chip has
an LPT port in it. More or less they get it for the price of the connector or
board header plus maybe a few protection devices.
