Just realized that 1.6.9 has already been released and it works! I can print now using the hp:/ backend without any errors appearing. But if I start hp-toolbox I still get these messages: --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Sep 16 17:46:07 vaio-z1 hpiod: unexpected DOT4CreditRequest: cmd=4, hid=1, pid=1, maxcredit=8: io/hpiod/dot4.cpp 144 Sep 16 17:46:07 vaio-z1 hpiod: unexpected DOT4CreditRequest: cmd=4, hid=1, pid=1, maxcredit=8: io/hpiod/dot4.cpp 144 Sep 16 17:46:07 vaio-z1 hpiod: unexpected DOT4CreditRequest: cmd=4, hid=1, pid=1, maxcredit=8: io/hpiod/dot4.cpp 144 Sep 16 17:46:07 vaio-z1 hpiod: unexpected DOT4CreditRequest: cmd=4, hid=1, pid=1, maxcredit=8: io/hpiod/dot4.cpp 144 Sep 16 17:46:07 vaio-z1 hpiod: unexpected DOT4CreditRequest: cmd=4, hid=1, pid=1, maxcredit=8: io/hpiod/dot4.cpp 144 ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
It seems that these messages don't influence hp-toolbox in any way except that it takes a bit longer to find the printer...
