Comment 28 for bug 368273

Bug still there as of 8-21-9 for Jaunty 9.04. Using the IP of the shared machine would not work for me.

ANOTHER WORKAROUND: Ubuntu Main Menu > Places >
  -Find the PC with the shared printer, and go into the shared "print$" subdirectory.
  -right click on any file/folder and choose "Properties"
  -Highlight the location, right click, and copy
 (on my network the directory copied was "smb://"PRINTER HOST PC NAME"/print$/ )

You will paste this directory into the printer set-up dialogue.

In New Printer Setup:
  -Choose "Windows Printer Via SAMBA"
  -In "SMB Printer" paste the complete directory you copied.
  This time when you click Browse and begin navigating the triangles, the directory will not bomb-out. Appears as though the pasted directory helps the browser find its way. Worked well repeatedly as I had to reinstall drivers to solve problems.
