CUPS provides everything the older Unix printer service did and a little more - such as authentication, automatic printer sharing and better interoperability. > What is the difference between lpr, lpd and cups lpr/lpd is simpler but less featured. lpr print facilities are provided by many printers and CUPS will interface with it when that is what is provided by the printer. However such interfaces have limited queuing functionality on network printers and no authentication/authorisation and limited accounting facilities as a result. > (I find that I have problems with cups on my wife's ubuntu and her > HP.

As noted the main problem being discussed is the default is to disable printers that are unresponsive for 5 minutes. It is only a default and the behaviour can be changed globally or per printer or per class. As HPLIPS is the driver, there can of course be problems with any printer drivers. I presume you needed a later driver? Since I assume a version is in the Ubuntu repositories somewhere. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
