Hi,
May be cable loose or heavy dust available in printer that`s why your printer not proper response it. Or may be printer main board damage position so i suggest you contact it printer technician or checking it, which area damage.

If your printer does not have a duplex unit then the printercannot print double sided pages automatically.
You can print double sided pages but you have to do it one page at a time.
First print Page 1 then place the page back into the paper tray, but turn thepage upside down and the print Page 2.
Then print page 3 on one side then page 4 on the other side and repeat for therest of the document.
I suggest you try a test page first, to get the printing the right way up onboth sides of the page so it reads correctly.http://www.fixya.com/support/r7325259-double_sided_printing_using_single_sided

You probably want to print a test page.
To print a test page with this printer:
Hold down the Go button (green button) for 5 seconds. You'll see an orange light flash, let go of the green button and a Self Test/Configuration page will print.

If the test page comes out ok, the printer is in working order. You just need to get a driver at http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=1845561&lang=en&cc=us&prodTypeId=18972&prodSeriesId=1845551&taskId=135

You need to program the paper size for the trays

This HP printer is comes with the USB cable. To install the printer software, you need to install the USB driver compatible to your printer and then it will ready to print.

Are you able to get a stand alone test page out of the printer? Hold the green button down for 5-6 seconds. It should print out a demo page. That way you can narrow it down to either a problem with the printer or a communication issue with your PC or network. Also, it would be helpful to know what the lights are doing on the printer when you try to print.

Open Printer options and reduce the print quality. It is probably 1200dpi. Make it 600 and try the print again.
You may also add more printer memory to print complex documents on highest resolution possible.

bottom light blinking means it is receiving data try to unhook cable power cycle and try test print with data cable unhooked if you wait should error out if does not print

Are you able to print a test page from the printer directly? if you are then check to see if the printer is set to Offline mode, if it's ok the I suggest you un-install the printer driver and re-install it again.

To print a Configuration page from the printer, press
and hold the Go button for 5 seconds
