List, I updated a gateway/router computer with Centos 5.6 and lost the ability to print pdf and tif files with the command "lp -d printer img.tif" This new unit replaced a Fedora 5 system that had been working well, and is still able to print pdf and tif files withing the same network. I have other Centos 5.6 gateway's at different facilities that print the pdf and tif files without a problem. All of these 5.6 systems have been updated without a problem. hpijs-1.6.7-6.el5_6.1.x86_64 has already been installed. I am at a loss in trying to see the difference between my 5.6 machines and would appreciate some advice as to where to look. Thanks much for your help. Greg Ennis
