possible screw-up installing HP printer

[John Lindsay <jclind@sentex.net>]

I just installed an HP Laserjet P1102w. I have the Hp status icon 
showing in the upper RH side of my toolbar. The printer icon shows up 
whenever I print something BUT I have the following folders and files 
residing in my Downloads folder and I want to know if I can just delete 
them or did I really screw up the installation of this printer by 
causing it to be installed in my Downloads folder?

Some of the folder names are 
'base','copier','data','fax','hplip-3.12.2', which shows a locked file 
and root only viewing, And even more files like align.py, cups_drv.inc, 
hp-hp.io, hpijs etc and a lot of libapdk_la files. Its only 65meg of 
files and folders but it is very messy and I would like to clean it up.
