Hi Luis,
Thank you for using Syncfusion products.
At present we do not provide support for silent printing of PDF document using ejPdfViewer control. However, we have added this feature to our feature request list and we do not have immediate plans to implement this feature. It will be available in any of our future releases. We usually have an interval of at least three months between the releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity.
Regards,
Mohan S
