Enable only manual paper feed for printers in Ubuntu

The following method is used to enable manual paper feeding option of HP printers in Ubuntu Linux.

1. Install required printer driver software while configuring new printers (Not all printers having drivers for Ubuntu. But HP providing that)
2. Open the HPLIB Toolbox program from menu
3. Under General section, select the value Tray1 (Manual) for the option called 'Paper Source' (Ref the image given below)
4. Save it and close.

From now on, the printer will wait for you to feed the paper even if you gave the print command. This may be useful when you need one side printouts for particular usage.

Note : This is tested under Ubuntu 11.10 with HP Laser set Printers.
