i use two basic types of inkjet decal paper; clear and white. clear for most stuff, white for some applications (but often would require precise trimming, which is dissuasive). thing with this stuff is you have to spray clear on top after printing else the ink will run and ruin your cool stuff. i've purchased semroc kits that have untreated inkjet decals. i scan all my kit's decals now prior to application just in case. i have no experience with laser printing of homemade decals.
