A solution …

To interfacing any USB scale like …
Mettler Toledo, Pitney Bowes, Fairbanks, X.J., CHARDER, Pelouze, SANFORD, DYMO, Endicia, ELANE XM, UNITED STATES POSTAL SCALES PS30USB/PS311 30-LB DIGITAL USB POSTAL SCALE

You can use the software BillRedirect like a driver ! This software can send the weight directly in any application .NET or can also support:
- Output weight to a Virtual Serial Port that you can use in your .NET source code.
- Output weight to an ASCII file that you can use in your .NET source code.
- Output weight to a TCP connection (client or server) that you can use in your .NET source code.
- Output weight to a UDP Broadcast packet that you can use in your .NET source code.
- Turn your USB scale to a wedge keyboard emulation.
…

It’s very difficult to get the API from manufacturing scale company ! Often they must buy SDK kit which was very expensive with a license agreement Grrrr. Right now I think that BillProduction is the only company that offer a compatibility with USB scales like a driver.

Can you reup the driver link? It shows Driver Not Found.

Thanks in advance.

The scripts here – how would I run them? I am windows savvy, but not developement competent at all! : )

The code is meant to be used by a software developer, who would embed it in a larger application’s code base. I could shove it into a simple executable, but it probably wouldn’t do what you want: it’d pop up a dialog with the current weight, but it wouldn’t be able to integrate with the USPS Shipping Assistant, since that would be code out of its control, and I doubt that that software has any sort of plug-in mechanism that allows new code to “hook into” the USPS software. I suppose it’s always possible that the latest update to USPS Shipping Assistant may have added native support for that scale, but I wouldn’t bet on it.

Of course, it probably would be possible to do some incredibly hacky solution of using the Windows Accessibility API to have this external code type the weight for you into the USPS Shipping Assistant, but that would probably break with each new update and version of the assistant that gets released.

My recommendations would be to use a USPS device that is supported, to actually use the Stamps.com service, since they obviously know how to read their own scale, or to continue fat-fingering the weight entry. Thanks to closed source software, that’s sometimes just how the cookie crumbles =)
