Hi there

Sorry for re-hashing old issues nut I'm having trouble installing an HP Deskjet F2483. I've downloaded the hplip-3.10.05.run but when I type the install command in terminal I get:
" angelo@angelo-desktop:~$ cd Desktop
angelo@angelo-desktop:~/Desktop$ sh hplip-3.10.5.run
Creating directory hplip-3.10.5
Verifying archive integrity...Error in MD5 checksums: 229f7298a99ba86153cad12fbc11b8a3 is different from 7c966612d669ecd8ec29df44dda0ae1f
angelo@angelo-desktop:~/Desktop$ "

Q: what is MD5 checksums and how do we correct their errors?

Many Thanks
