Currently Ubuntu have the following HPLIP versions in universe pocket:
trusty (14.04LTS) (utils): 3.14.3-0ubuntu3.4
xenial (16.04LTS) (utils): 3.16.3+repack0-1
bionic (18.04LTS) (utils): 3.17.10+repack0-5
cosmic (18.10) (utils): 3.18.7+dfsg1-2ubuntu2
disco (19.04) (utils): 3.19.1+dfsg0-1
eoan (19.10) (utils): 3.19.6+dfsg0-1ubuntu1
focal (20.04): 3.20.3+dfsg0-2
This leads to the following variants.
(a) Required HPLIP version ≤ repository HPLIP version
So if one sees that Min. HPLIP
Version is lower or equal to the version of the HPLIP package from repository, then the installation of the following packages will be enough with:
sudo apt-get install hplip hplip-gui
(b) Required HPLIP version > repository HPLIP version
If one sees that Min. HPLIP
Version is greater than the version of the HPLIP package from repository, then then one needs to install binary HPLIP by following my other answer.
(o) Optional HPLIP binary/proprietary plugin/driver
If one sees that Driver Plug-in is set to yes (or required), then one needs to install the binary/proprietary plugin/driver by following my other answer.
Examples for Ubuntu 18.04 LTS (hplip 3.17.10) and some HP device models:
| Model Name | Min. HPLIP Version | Driver Plug-in | Action |
| HP LaserJet 6l Printer | 0.9.5 | No | (a) |
| HP LaserJet Pro MFP m426fdn | 3.15.11 | Required | (a)+(o)|
| HP Tango | 3.18.12 | No | (b) |
