Hi,

Thank you for your help and support.
This is pretty old printer - but it is a great, great workhorse. However, it does not have USB and mine does not have a Network card. 

I went through the entire doc and followed it through, still same error:
tsp0001@tsp0001-desktop:~/Desktop/hplip-3.9.8$ /usr/bin/hp-setup

 HP Linux Imaging and Printing System (ver. 3.9.8)
 Printer/Fax Setup Utility ver. 9.0

 Searching... (bus=par, search=(None), desc=0)
 error: No devices found on bus: par

I also noticed this: When I go to:
        - Applications
                  Accessories
                          HP Device Manager
     And click on it - it brings me HP Device Manager. There is a Printer icon there (left side) and it has "red x" on the top of the icon. When I click on HP-Device Manager - Display Information - it displays this:
        Unable to open device
                             hp:/par/HP_LaserJet_4_Plus?device=/dev/parport0

Stuck again

> Note: hp-check can be run in three modes:
> 1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the
> proper dependencies are installed to successfully compile HPLIP.                                                                             
> 2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP    
> supplied tarball has the proper dependencies installed to successfully run.                                                                  
> 3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time  
> dependencies).
