Scanning with hp-scan, scanimage or xscan fails because libhpmud.so is needed, which is removed during the RPM install stage: strace of e.g. scanimage 'hpaio:/net/HP_LaserJet_M1522nf_MFP?ip=10.0.0.21' shows: open("/usr/lib/libhpmud.so", O_RDONLY) = -1 ENOENT (No such file or directory) Building a new RPM that just doesn't remove libhpmud.so fixes the problem. See http://lists.debian.org/debian-printing/2009/02/msg00067.html for an equivalent bug report for debian.
