Hi Polly,
Thanks for contacting support.
Aspose.Pdf for .NET supports the feature to printing PDF documents and In case your requirement is to print pages of single PDF file to different trays, I am afraid this feature is currently not support. For the sake of implementation, we already have logged this requirement as PDFNEWNET-34180 in our issue tracking system. As soon as the feature becomes available, we would be more than happy to update you with the status of correction. Please be patient and spare us little time.
We are sorry for this inconvenience.
