Printer Output is Written to Disk

Solution:

To send output to a physical printer, you must map the filename using the dd_LPT1 environment variable or, if your system supports the lp printer spooler, you should use:

dd_LPT1=">lp";export dd_LPT1

See the section Filename Mapping in the chapter Filenames in your File Handling book for full details of filename mapping.
