The hplip, hpijs-1.6.7-4.1.el5 and libsane-hpaio-1.6.7-4.1.el5 will throw the conflict error. If you don't have following devices you may remove these packages. The hpijs is a collection of optimized drivers for HP printers. hpijs supports the DeskJet 350C, 600C, 600C Photo, 630C, Apollo 2000, Apollo 2100, Apollo 2560, DeskJet 800C, DeskJet 825, DeskJet 900, PhotoSmart, DeskJet 990C, and PhotoSmart 100 series. The libsane-hpaio has SANE driver for scanners in HP's multi-function devices (from HPOJ). If you don't have any other devices from list please remove these packages to install hplip. # rpm -e --nodeps hplip # rpm -e --nodeps hpijs # rpm -e --nodeps libsane-hpaio 2. Install the following package from RHN to satisfy dependencies for hiplip-3.10.6_rhel-5.0 : # yum install net-snmp-libs # yum install sane-backends-libs 3. Install the latest hplip package. # rpm -ivh hplip-3.10.6_rhel-5.0.x86_64.rpm -- Hakan (m1fcj) - http://www.hititgunesi.org
