Unable to utilize the Printing API in Rho 4.1

Unable to utilize the Printing API in Rho 4.1 // Expert user has replied. R Ryan Collins 3 years 7 months ago 2 1 0 I have upgraded to Rho 4.1 in attempts to utilize the new Printing API. I have had zero success. I have attempted both the JS samples and a rough Ruby implementation to connect to my Bluetooth printer. I have added the "printing" extension to my build.yml. I receive the following errors when attempting to call into the API... JS implementation: Error when calling "Rho.Printer.searchPrinters": TypeError: 'undefined' is not an object (evaluating 'Rho.Printer.searchPrinters') Ruby implementation: When attempting to call "Rho::Printer.searchPrinters": I receive "Error: uninitialized constant Rho::Printer". This project was actually created using 2.2.0 and upgraded to 4.1 just recently. Any advice would be appreciated. Thanks! Ryan

Hi Ryan, We only support Zebra printers right now. You have to add to extensions to the build.yml:

extensions: ["printing","printing_zebra"]

The error above indicates that the JS object is not found. So make sure you build with the 'clean' option checked. Take a look at this guide:
