http://ubuntuforums.org – I have an issue setting up a network printer that formerly worked and for some reason no longer works. It could be from a recent update or a conflict I'm not sure. I would appreciate some insight from the community on this issue. First off the printer in question is full operational. Test prints from other window's machines are successful. Test print from a Mac OSX also was successful. My original settings for the network printer were setup through default Printer configuration - localhost. I had to set up the printer under the "Other" option and put in a Device URI: hp:/net/HP_LaserJet_4050_Series?ip=128.194.169.134 Make and Model: HP Laserjet 4050 Series Postscript (recommended) I have attempted to delete the printer and after a full restart add the printer again. That doesn't seem to work. After some investigation I went to the hplib site: http://hplipopensource.com/hplip-web...ies.html#note1 Downloaded the installer file and installed it. When attempting to setup the printer through the HP GUI Device Manager it throws the error: "Device not found. Please check connection and power-on device" even when attempting to connect through the advance manual option. The printer's IP and Domain name both communicate through ping from this computer so obviously I can see them network wise. I attempted to run the hp-check -t command to see if gave some insight on the error: Quote: HP Linux Imaging and Printing System (ver. 3.9.8) Dependency/Version Check Utility ver. 13.0 Copyright (c) 2001-7 Hewlett-Packard Development Company, LP This software comes with ABSOLUTELY NO WARRANTY.

Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies installed to successfully run. 3.

Please refer to the installation instructions at: http://hplip.sourceforge.net/install/index.html It doesn't look like it gave any insight. I haven't printed anything from the computer in a few weeks so whatever messed up my ability to print could have happened with any number of package updates or something else. I tried reinstalling packages through Synaptic including CUPS and HPLIP related packages. Any ideas on a direction I could take? Thanks! (Hardware)
