Laser-fluorescence spectroscopy and the laser-rf double-resonance method are combined to classify lines in the Pr I absorption spectrum. The double-resonance technique is found to be particularly valuable for this purpose since, by focusing on the lower level of a transition, it leads in many cases to unique line assignments. Precise (approx.1 ppm) measurements are reported for the hyperfine-structure (hfs) constants of 15 low levels, and 0.5% values for 34 higher levels. Classifications are given for many lines in the region 5746
