Failed to start scanner: Invalid argument

[nobody13]

When I try to scan i get 'Failed to start scanner: Invalid argument'.

i'm using : net-print/hplip-3.17.10 and media-gfx/xsane-0.999-r2 on Gentoo

I't seems the drivers are ok. When I run # scanimage -L:

device `hpaio:/net/HP_LaserJet_Pro_MFP_M26nw?ip=192.168.1.148' is a Hewlett-Packard HP_LaserJet_Pro_MFP_M26nw all-in-one
device `hpaio:/net/Officejet_7300_series?ip=192.168.1.145' is a Hewlett-Packard Officejet_7300_series all-in-one

I can scan from the OJ-7310 just fine. I can scan to the laserjet if I use a differnt program (simple scan) but not from the Hp device Manager which uses xsane. Is there some config file hidden somewhere for xsane that i need to set manually?

I found this in /var/log/messages:

There is a [hp_laserjet_pro_mfp_m26nw] section in that models.dat file mentioned above. Is it possible th 'hp_' part of that entry is causing it to be ignored? I edited out "hp_" and the printer was no longer availabe.

I don't know about the library error but libm.so is present

/lib32/libm.so.6
/lib64/libm.so.6
/usr/lib32/libm.so
