What is the JRPRINT file format?
Files with the .jrprint extension are associated with JasperReports - an open-source Java library designed for creating reports. A .jrprint file represents the final rendered report: it stores the fully populated output - headers, footers, page layout, text and images - after live data has been merged into the report design. Technically, each file is a serialized Java object (net.sf.jasperreports.engine.JasperPrint) written in standard Java Object Serialization format, opening with the binary magic bytes 0xACED.
Cooperation of .jrprint and .jasper files
The .jrprint format sits at the end of the JasperReports pipeline. A report design begins as a .jrxml source file, which is compiled into a .jasper binary template. At runtime the JasperReports engine fills that compiled template with live data and writes the result to a .jrprint file. Both .jasper and .jrprint are elements of the JasperReports suite, but they are assigned different functions: .jasper holds the compiled design template, while .jrprint is the finished, print-ready document.
Conversion and display of .jrprint files
Using the JasperReports library enables conversion of the .jrprint format to more widely used file formats, such as PDF, HTML, XLS, CSV, RTF and XML. An alternative XML-serialized form of the same output is saved with the .jrpxml extension. .jrprint files have no restrictions concerning operating systems - they can be displayed in Windows, macOS or Linux environments wherever a compatible Java Runtime Environment is available.
Security & safety
RISK: MEDIUMA .jrprint is a serialized Java object, and deserializing untrusted serialized Java is a known security risk (object-deserialization attacks). Only open .jrprint files from sources you trust, inside the JasperReports tooling, and keep the library up to date. The file itself runs nothing on its own, but never feed an unknown .jrprint into a custom JRLoader path in a service that processes external input.
Format details
in a nutshellPrograms that open JRPRINT files
Windows2 apps
Jaspersoft Studio
Free Open the .jrprint in the report viewer (or via the Preview), then Export to PDF/XLS/HTML/CSV.
JasperReports library (Java app)
Open-source Load with JRLoader.loadObject(file) then JasperExportManager.exportReportToPdfFile(...) to convert. 
macOS2 apps
Jaspersoft Studio
Free Same as Windows - open the print file and export to a common document format.
JasperReports library (Java app)
Open-source Use JRLoader + JasperExportManager from a Java program to render/export the file. 
Linux2 apps
JasperReports library (Java app)
Open-source Programmatic load and export via the JasperReports engine. Technical details
deep spec| Format type | Serialized Java object - a net.sf.jasperreports.engine.JasperPrint instance stored in Java Object Serialization format |
| Magic bytes | 0xAC 0xED 0x00 0x05 - standard Java Object Serialization Stream header at offset 0 |
| MIME type | application/octet-stream |
| Developer | Jaspersoft (now Cloud Software Group, formerly TIBCO Jaspersoft) |
| Pipeline stage | End-stage output: produced after the JasperReports engine fills a compiled .jasper template with a data source |
| Human readability | Binary, not human-readable; must be opened via the JasperReports API or Jaspersoft Studio |
| Compressed variant | Can be written as GZIP-compressed binary; the .jrpxml extension denotes an equivalent XML-serialized form of the same content |
| Export targets | PDF, HTML, XLS/XLSX, CSV, RTF, DOCX, ODS, XML, JSON and plain text via built-in JRExporter implementations |
| Runtime dependency | Java Runtime Environment (JRE) with the JasperReports library JAR on the classpath |
| Version sensitivity | Tightly coupled to the generating JasperReports library version; files may be unreadable by significantly older or newer library versions |
| Stored content | Fully rendered pages including text, images, charts, barcodes, lines, rectangles and precise layout geometry |
| Cross-platform support | Runs on any OS with a compatible JRE: Windows, macOS and Linux are all supported |
| Export API | net.sf.jasperreports.engine.JasperExportManager and the JRExporter interface and its implementations |
| Related formats | .jrxml (design source), .jasper (compiled template), .jrpxml (XML-serialized print file) |
| Released | Early 2000s with the JasperReports library (first release 2001) |
