Printer connectivity failed with system, check connectivity

I assume that printer is perfectly installed and
for both side printing,

go to
contro panner ->printer and faxes->right click on printer->select properties->at bottom click on preferences -> choose "duplex printing".

if you cannot duplex printing here need to install duplex printing.

Hello, Have you checked the print driver properties, Under the device settings to be sure the duplexer has been enabled.

go to HP Support & Drivers 1

Print out the configurationpages and there you'll find the MAC adres.Use the arrow down button to scroll to the informationmenu, scroll down to "print configuration" and press the green button.

you may use a non genuine toner cartridge, check another working cartridge

HP LaserJet P3005 Printer Series - Service Error 49.0E00 when Printing PDF Files from Mac 10.5
Issue
A Service Error 49.0E00 message appears while printing PDF files from Mac 10.5 with the EconoMode setting enabled from the printer control panel and using the printing presets with the EconoMode setting disabled.
Solution
Recommended action:
Disable the EconoMode setting from the printer control panel (the default setting is OFF ).
Select printing presets with the EconoMode setting disabled.
Try performing a test print from PDF files in the computer to check for the results.
NOTE: If it is required to use a printing preset with the EconoMode feature turned off, ensure that EconoMode is set to OFF from the printer control panel also.
