Hi,
The error code: 3012 is actually a windows error which indicates that the specified printer is not found. Please try installing the respective printer driver on the system where the application is running and see if it works for you.
Also make sure to have sufficient permissions on your application to access the specified printer.
Our API is just passing the error it received from the printer/spooler to the client application.
Thanks,
