[Inkscape-user] simple pattern fill won't print, but it shows up in Inkscape

Hello all,

I'm getting the hang of Inkscape after using it for a few months. All is going well, but I'm hung up on a problem with pattern fills.

Here's the situation:

I'm running Inkscape .41 on a Debian Linux system (unstable).

I have a document with a simple cross-hatch pattern fill. (I actually borrowed it from this helpful tutorial: http://www.carto.net/papers/svg/samples/patterns.shtml)

The pattern fill shows up properly in Inkscape, but it's not visible when I print. I don't think it's a problem with my printer driver, as I've printed both to the actual printer (Lexmark E210) as well as the generic CUPS-PDF printer, which generates a PDF file. In both cases, the shapes in which the fill should appear are simply white.

I've attached the file--it's only a few KB.

If anyone is able to help, I'd much appreciate it.

Thanks kindly,

Charles.
