LinuxQuestions.org - Help with Install of foo2zjs for HP 1020

I installed the HP laserjet 1020 the other day and the test page worked fine. Now I wanted to print some documents and nothing is happening. It says that it is ready to accept jobs. I have checked my connections, and cycled the power on and off to no avail.
I really don't know what to do. Any thoughts.
I have read the linuxprinting.org pages for the Laserjet 1020, I am sorry but I don't know where to start. Should I first uninstall the the HP then go thru recommended procedure.? For Ubuntu is suggests the following;
UBUNTU NOTES
------------
Install build-essential FIRST:
$ sudo apt-get install build-essential
$ make
$ sudo make install
$ sudo make cups

Could someone explain what I am doing here, as this is all new to me.
Then should I follow this procedure ;
INSTALLATION
------------
Unpack:
$ wget -O foo2zjs.tar.gz http://foo2zjs.rkkda.com/foo2zjs.tar.gz
$ tar zxf foo2zjs.tar.gz
$ cd foo2zjs

Compile:
$ make

Get extra files from the web, such as .ICM profiles (for color correction)
and firmware. Select the model number for your printer:
$ ./getweb 2600n # Get HP Color LaserJet 2600n .ICM files
$ ./getweb 2430 # Get Minolta 2430 DL .ICM files
$ ./getweb 2300 # Get Minolta 2300 DL .ICM files
$ ./getweb 2200 # Get Minolta 2200 DL .ICM files
$ ./getweb cpwl # Get Minolta Color PageWorks/Pro L .ICM files

$ ./getweb 1020 # Get HP LaserJet 1020 firmware file
$ ./getweb 1018 # Get HP LaserJet 1018 firmware file
$ ./getweb 1005 # Get HP LaserJet 1005 firmware file
$ ./getweb 1000 # Get HP LaserJet 1000 firmware file

Install driver, foomatic XML files, PPD files, and extra files:
$ su OR $ sudo make install
# make install

If you use CUPS to manage your printers, you must restart cupsd:
# make cups OR $ sudo make cups

Again I am a relative newbie and I don't want to mess things up.
Any help would be greatly appreciated.
