Connecting a Printer 
LPT
 
A printer can be connected via the 25-contact parallel interface LPT at the 
rear of the instrument (recommended) or one of the serial interfaces COM 1 
or COM 2. For the interface description see section "Hardware Interfaces" in 
chapter 8.  
 
 
The printer type and port must be set in the Print tab of the Setup menu:  
 
 
 
!  To open the Setup – Print tab press the SETUP key at the front of the 
instrument and activate the Print hotkey at the lower edge of the screen. 
! In the Printer section set the printer type and port (COM 1 or COM 2 for 
the serial (RS-232) ports; LPT 1 for the parallel printer port). 
It is recommended to connect the output device to the parallel interface LPT, 
if possible: With this selection, configuration of the interface is not 
necessary; besides, the serial connectors may be used for GPIB bus etc.
