It's a USB printer (Canon MP750) that I share amongst 4 other Ubuntu machines (all now running Feisty 7.04). Printing to the machine from all systems works fine both via the new Feisty MP750 driver and the existing Turboprint driver (although it took some uninstalling & reinstalling to get the Turboprint driver working correctly). Unfortunately, it seems that since 7.04 all of the printers on this machine are now shared amongst the other machines. I can't seem to figure out how to only share this printer, but not the other locally installed virtual PDF printer, fax printer etc. Here is what happens: 1. Printers are set up on this machine - mostly via localhost:631 (cups) as the System|Administration|Printers wizard doesn't seem to want to allow me to delete old printers or add new ones properly. 2. Via localhost:631 I 'unpublish' my virtual PDF printer etc., and only keep my MP750 published. 3. On the other 7.04 machines, they all pick up every printer on this machine; the MP750, the virtual PDF printer, and the fax printer. That's part of the problem; I only want them to pick up the MP750 and not the other printers.</blockquote><div> I am not using Feisty, but with both Edgy and Dapper, I have experienced strange behavior and inconsistencies when using Cups' web-based administration... If you type this command (on the PC where the virtual PDF printer and fax printer are hosted): $ lpoptions -p name_of_virtual_printer What is the value of the 'printer-is-shared' option? If it is '0', try restarting cupsys wait a couple minutes and the from one of the other machines, try: $ lpstat -p Does the printer still show up on the remote PCs? If it is '1', try manually changing the printer's 'Shared' directive to 'No' in /etc/cups/printers.conf, restart cups, and try 'lpstat -p' again (from another PC). Does the printer still show up on the remote PCs? </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">If I try to add a local virtual PDF printer to the second (or other Ubuntu 7.04) machine via the System|Administration|Printers wizard, it will not add a local PDF printer. (cupsys* and cups-pdf are intalled just fine). If I add a local virtual PDF printer back into this machine, it shows up on the other machines, and I can print to it from those machines. But as expected the print output goes back to this machines /PDF directory path. </blockquote></div> Assuming you get the sharing issue worked out, check to make sure the cups-pdf URI and PPD exists on the other PCs where you want to set up the virtual PDF printer: $ lpinfo -v | grep pdf file cups-pdf:/ # expected output... use with -v option when adding printer using lpadmin below $ lpinfo -m | grep cups-pdf cups-pdf/PostscriptColor.ppd Generic postscript color printer rev4 # expected output... use with -m option when adding printer using lpadmin below Then to actually add the printer (subsitute 'PDF-Creator' with desired name): $ lpadmin -p PDF-Creator -E -v cups-pdf:/ -m cups-pdf/PostscriptColor.ppd -u allow:all -o printer-is-shared=no Notice the -o option at the end of line... this will head off trouble before it begins! :) Let me know if this helps. -- Mitch
