This is not the first post from us regarding a connection problem between a RhoElement App (version 2.2) and a Zebra GX420t printer. Finally we now get the error log so we can share with you in case you have a solution. Our major problem is that our Apps is critical so when printing fails it is a big trouble. Our end user use a web form so when is filled they press a Save and Send button, then all data is sent to us using RhoConnect, at the same time data is sent to the printer. Data is sent successfully to our servers however randomly the printer fails, and data filled in the form is lost, so we are able to try to printer again.
I have attached the log from the ET1. Any help is highly appreciated.
