typical: This Printer works in Windows, also with Katya (good girl) even in LMDE the pre 18.104.22.168 kernel. But as soon as Pack 3 was applied to update to 22.214.171.124 the printer became invisible to the printmanager.
Sitting right beside it, the Epson Workforce, also connected through USB, was immediately detected, had no problem installing whatsoever.
whats especially confounding was that $ lsusb showed all usb devices, INCLUDING the hp 3030, the dmesg catalog listed it, so, the system saw the printer, only the printmanager did NOT, hence, I could not install it.
What fixed it? install package hplip and hplip-cups!
(you know, go into Software manager type 'hplip' into the search field) and there they are.
I wish there had been a pointer somewhere in the literature, it would have saved me a lot of time.
