There is only one file type that uses the .JRPRINT extension:
JasperReports Print File
File created by JasperReports, an open source programming library in Java used for creating reports; contains all report content such as headers, footers, page layout, text, and images; used in conjunction with a .JASPER file to "fill" a report with data from a data source.
JRPRINT files can be converted programmatically into a variety of formats using JasperReports, including .PDF, .XLS, .CSV, .RTF, .TXT, .XML, and .HTML.
