I successfully installed my HP M1132 MFP printer by running
hplip-3.15.11.run script. On Mint 17.3 Beta and Debian 8.2. The printer, including scan, works. What's more, I didn't get into any kind of trouble while installing it. Seamless.
There is just one thing. It didn't tell me in the end, if I may delete those 3548 files created inside the folder, where I ran it, while installation. So, I my question is - may I? Did it install locally into the folder or into the system?
