When specifying a printer by IP address
c:\>lpr -S [printer's IP address] -P [Option] -o l \path\file name
When specifying a printer by host name instead of IP address
c:\>lpr -S [printer host name] -P [Option] -o l \path\file name
To print a binary file, include the “-o l” switch (a dash followed by a lowercase O and L) after the printer name.
