Re: hp-setup does not find usb printer
The bugreport has been followed by a few exchanges and finally I have downloaded the rpm package and 'manually'compiled, built and installed the hplip package. This resulted, yesterday, in a functioning printer:
Testpage was printed successfully as well as a one-page text in from LibreOffice.
In the evening the pc and the printer were switched off.
Today, after starting up oS-11.4, printing was not possible. CUPS had a (by now well-known) error message: "/usr/lib/cups/backend/hp failed".
Maybe unwisely, I have used Yast to delete the printer and tried to re-install by starting with Yast and then clicking on "use hp-setup". The printer was not recognized until I entered its usb location (002:003). At the next step a click on "add printer" was succesfull. However, printing failed with the above Cups error message.
Next: removed printer as before. Then deleted all files produced from the rpm package (NOT the downloaded rpm package itself) and again did the compile etc. sequence. This ends in hp-lip starting. Again, printing failed.
Right now, I am pretty sure of the following;
1. The hardware, including usb-cable and usb-socket is ok.
2. No software modules are missing,
and I have a strong suspicion that hplip has a problem in dealing with the usb and that this is associated with libusb.
On an Ubuntu forum I found the suggestion that there was a regression problem in a recent version of libusb, but I could not match the versio numbers with those in oS-11.4.
Conclusion: more head scratching may help :-)
