Mac Os X 10.6.8

Unfortunately, 2-sided printing is only available for the Epson L20 when used with the Windows OS. See page 22 of the user guide available here: https://www.epson.com.ph/Ink-Tank-Printers/L-Series/Epson-L120/s/SPT_C11CD76401?review-filter=Mac+OS+X+10.11.x#manuals . The current link to the manual is http://support2.epson.net/manuals/english/ij/l120/pdf/npd4965-00.pdf . You might be able to use the Duplex feature if you install BootCamp and an licensed version of Windows (XP up to WIndows 10). Neither BootCamp or licensed copies of Windows are free.

I wish that I had better news for you.

Ok this might not be much help but there is an option in the menus to 'print without authentication' you need to go to the control panel on the copier, press the utility/counter button to the right of the touch screen, press administrator settings for which the password is 12345678 then press number 4 user authentication/account track, then number 4 print without authentication, if you turn this option on it will allow you to print from mac, you will need to confirm this with whoever checks the account track as it may not then monitor any of the print jobs. Hope this helps

Description
LPR (line printer remote) is a platform independent printing protocol that is associate with TCP/IP. It works by using LPR client software that communicates to a server running LPR services.

In terms of PSU, LPR printing will become the basis for all network printing while Novell print queues are phased out. Therefore, all Macintosh, Windows, and Unix computers will be configured to print through LPR.

Requirements

· LaserWriter print drivers version 8.5.1 or newer

· The Macintosh must have a working TCP/IP networking configuration. (If the Mac can browse the web then it's working.)

· a server running LPR services or a printer that supports LPR printing. Most HP LaserJet printers support LPR. However, only the following LaserWriters support LPR printing:

- LaserWriter 8500
- LaserWriter 16/600 PS
- LaserWriter 12/640 PS
- Color LaserWriter 12/600 PS

What MAC OS are you using? I don't remember for OS 9 and earlier but if you are using OS X I can help you out. First make sure you are using the latest version of the print driver. When you open a document to print and select the Kyocera printer you will see the print dialog box. You need to look under the printer specific options to find the job accounting. I believe it is under set 2.

Hope this helps.
