We have migrated our systems from using DayPilot to Telerik but there is a feature available in DayPilot which is lacking from radschedule and there is a lot of demand from our customers to re-enable this feature.
Would it be possible to provide some sort of export to an image file which would be in a suitable format for printing.
This could work by having an Appointment Item Printing Template, which could only contain very basic mark-up to simplify the task of creating the images.
An example of this in DayPilot is showing here.
