First, disconnect your printer from your computer before following these instructions.
Then select a print option from the printing section of the setup menu. Obsession Off-Line will generate an error, saying that it could not detect a printer connected to the printer port.
Now exit Off-Line. It will create a file called "prn01.$$$" in the "OBSN" folder containing the information you wanted to print. This is a temporary printer cache file that you can copy and open in any text editor. Be aware that this printer cache will be overwritten every time you try to print without a printer connected.
