First be sure the oscilloscope is on the LAN, then go to the oscilloscope's Utility/System/Hardcopy menu and select the Format appropriate to your network printer (For example the Lexmark Optra Lxi is a postscript printer, so a user of that printer would select the EPS format), set Options to Portrait, Ink Saver On, and Port to Ethernet. Next, go to the scope's Utility/System/IO menu, select Ethernet Printer Settings and enter the printer name, server name, and server IP address. For example: Printer Name: OPTLXI Server Name: Print Server1 Server IP Address: 128.181.144.141 Finally, click OK Accept and clear the menu. Then press the scope's print button to initiate the print.
