OK, so the error message occurs with all the following conditions:
- One particular workstation
- Adagio Invoices specification
- Default printer not kept, but changed in Setup
This error message is trying to find something in a list and is unable to. We have had one other report of this error when changing the printer from the Setup for Adagio Invoices to print to a different tray, and the problem went away when the client uninstalled and re-installed the printer on their server.
Does the same error occur if you use a different invoice specification to print/preview the invoice?
If you visit the File/Options within Adagio Invoices and specify a 'specific' printer - the one you are changing to within the Setup area - does the problem still re-occur?
Does any other workstation print to this identical printer with Adagio Invoices?
Is Terminal Services or Citrix involved? Could the printer driver name change? If so, check out this Citrix article
here. The solution is changing something in the network, not Adagio.
If you continue to get the error, please describe the working enviroment (Windows version, network type, local/shared printer, File/Options settings, etc).
