ASP.Net Website project fails to build after updating a referenced DLL

So I have an ASP.NET VB website that references several other projects (their DLLS are just put in the site’s bin folder). I need to update a small piece of code in one of the projects, which I have done and it builds fine. However, when I copy over the new DLL to the website’s bin folder it fails to build, and all the Imports statements say “BC40056: Namespace or type specified in the Imports xxx doesn’t contain any public member or cannot be found”, which results in a ton of errors like “is not defined” . There is no reference to the updated DLL in the website project’s properties, but if I put the old version back it’s all fine.

How to send a picture (or retrieve from printers memory) through raw IPL?

I am printing labels on an Intermec printer via IP and have been asked to add our company logo to the label. In other applications I am able to break apart a bitmap and send raw ZPL, but I can’t figure it out in IPL. I would also settle for saving the image on the printers, but I can’t figure out how to retrieve it to print.
Here is my simple procedure, any help would be great!
