I discovered how to use that printer - and probably many other models - via LAN from windows™ clients:
Once the drivers are installed locally in windows, they can be used over network via Samba!

Linux clients can print via network protocols, which are integrated in Cups

Here's the recipe:

• Get cups up and running:
  • sudo apt install cups
  • HP says: hplip in debian repos is fine
  • Black print works perfect, color prints are problematic with the open source drivers
  • You might try HP's linux drivers: http://hplipopensource.com/hplip-web/install/install/index.html
  • If you don't have a graphical environment on your server: run 'hp-setup -i' to install driver from in a terminal

• Share the usb printer via samba (nothing special) see smb.conf
  

• Check the web-interface at http:<hostname or ip>:631 - the printer should be there already. you can set default options. * To use the printer from Linux clients over network, you just need the URL of the printer. There are various protocols and drivers. The URL is listed in the printer page of the web-interface and might look like this: Connection: hp:/usb/HP_Color_LaserJet_CP1215?serial=LJ1WEZ1
  * Use this URL to add a printer in your Linux desktop. Most times the printer setups find new printers automatically (via cups-browsed).
  
  <Location /admin> Order allow, deny Allow from 10.10.10.* </Location> == windows™ client setup: == * boot XP [best in a virtual machine: e.g. virtualbox version from sun handles usb 2.0 devices perfectly ] * get “full package” of drivers & “HP toolbox”: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=de&lc=de&dlc=de&product=3422476works) * it is required to plug the usb-cable of the printer into the windows box during driver installation!! * connect to the linux server printer share from explorer: \\<hostname>\ - doubleclick printer * now windows asks for the driver files and they are available now from the previous local installation! * choose “select model” → HP → scroll to the end of the list, find “HP Color.. $your-model”, enjoy!
  == +++ == * the windows driver contains 100s of profiles for all kind of papers * color-prints work much better * the “HP Toolbox” offers many options to setup the printer == linux bugs == * sometimes the printer stops to work - e.g. after system updates - with errors like “Filter missing” or “requires proprietary plugin” * FIX!: run 'hp-setup -i' to install driver from HP!** - install and press “resume printer” in webiface
