I had a HP P1102W-printer installed on my Ubuntu 14.04. I used some program from HP that already had the drivers (no download) and made a successful installation... no issues.
After formatting the HDD and reinstalling the OS I could not find that HP-program again but tried HPLIP instead (3.15.7 and 3.15.6). But HPLIP can not find or download the necessary plug-in.
I have tested the "hp-doctor" that suggest that I should download the missing driver from internet/ HP-server. But all efforts ends with the same error message.
Error message:
Checking for network connection...
Downloading plug-in from:
error: Plugin download failed with error code = 8
error: file does not match its checksum. File may have been corrupted or altered
Any suggestions?? Is this problem with my PC or is it with the HP-server. Can the old installation program from HP be found somewhere (not HPLIP)?

No matter what HPLIP I run will work as long as the source server is not working.
