Convert PRN to ODS

Old Lotus 1-2-3 documents or spreadsheets (including .prn files) are still supported in some modern spreadsheet software, usually in productivity suites based on Open Office. But not all .prn files are spreadsheets, some are just printer outputs and these cannot be opened just printed. There are print drivers available that allow printing of old .prn files on your printer device, you have to check out your vendor for these.
