Printer can't print Landscape
Certain applications or programs will require you to turn on LPR Port Monitor to print Landscape.
The Line Printer Remote (LPR) Port Monitor allows a computer running Windows Vista, Windows 7, Windows Server 2008, or Windows Server 2008 R2 to print to the Line Printer Daemon (LPD) service on a UNIX print server.
You do not need to install the LPR Port Monitor to print to a printer or print server using the LPD protocol, unless the print server is a UNIX print server. To use a computer that is running Windows Vista, Windows 7, Windows Server 2008, or Windows Server 2008 R2 to print to a printer or print server that uses the LPD protocol, you can use the Network Printer Installation Wizard and a Standard TCP/IP printer port, which is faster than an LPR port.
