Im trying to get the SDK\Print Server API Samples\WebLabelPrint

project to work in a production IIS server. The web site comes up, if I click on the printers it displays all of the printers so it appears to be accessing the sdk ok. However when I go to print one of the sample labels in the sample app, I get this error message.

Could not load file or assembly 'Seagull.Services.PrintScheduler.Contracts, Version=11.0.9.1, Culture=neutral, PublicKeyToken=109ff779a1b4cbc7' or one of its dependencies. The system cannot find the file specified.
