You could use PDF::API2 or PDF::API2::Lite, for example.  Or you could create a little text file with some PostScript code, and send it to your printer, or view it (or create a PDF from it) with Ghostscript. Adjust the parameters as appropriate. The sample creates equidistant lines, but it could easily be modified to print any other pattern...
