Thanks again, Alkis. I subsequently found https://help.ubuntu.com/community/UbuntuLTSP/localprinter (updated 2015-04-08), but it turns out that even its specified configuration is not needed. I was tripping on the fact that trying to run system-config-printer on the client results in a BAD REQUEST error, but this seems due to regular users not having privileges to configure printers. All that was needed was to run system-config-printer on the server, and under Server: Settings check "Publish shared printers connected to this system." I may have also needed to update the client image, but probably not. I am not using /etc/cups/client.conf or ~/.cups/client.conf. After that, the server-connected printer automatically shows up in any app's Print dialog. Various references also say to check "Show printers shared by other systems," but that setting is no longer presented under the current version of system-config-printer. Interestingly, I got no discernable results from setting CUPS_SERVER=<ltsp-server> or KEEP_SYSTEM_SERVICES=cups in lts.conf. On the fat client, cups was running even without the KEEP_SYSTEM_SERVICES line. And setting CUPS_SERVER in lts.conf did not set up this environment variable on the fat client. ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _____________________________________________________________________ Ltsp-discuss mailing list.
