====== Install old printer on Linux ======
Standart installation pack don't work. There are still errors. In my case Konica Minolta pagepro 1490MF (mfprinter, Laser Pro LL2).
Mostly may be problem in 32 vs 64 libraries, so this may helped in many cases:
sudo apt-get install libcupsimage2:i386
In my Konica Minolta pagepro 1490MF case after install official (very old) driver, I need also this:
sudo apt install lib32stdc++6
sudo rm /usr/lib/libstdc++.so.5
sudo ln -s /usr/lib32/libstdc++.so.6 /usr/lib/libstdc++.so.5

When you try to find problem:
sudo tail -n 200 /var/log/cups/error_log
When you see, that some filter has a problem (your system may say Filter failed), look at the log and then into problematic filter, eg.
readelf -d /usr/lib/cups/filter/rastertoprinterbin
You'll see which shared library needs - there may be problem.
Maybe you need install ''libjpeg62:i386'', etc.
