Labeling Negative Files

Not sure what the title should be but I thought sharing how I label my print files would be helpful. Back in the 80's I used a software that created labels for slides and came with labels for dot matrix printers these also worked great for labeling negative sleeves. Since getting back into shooting film I have been looking for something that could do the same and using fine tip markers were PIA.
I found this portable label maker by Epson Label Works series and has worked as I intended. I use the LABELWORKS PX Standard 3/8" (9mm) and this fits perfect on the top info area of the 135 and 120 film sleeves. Hope this info helps.
One issue was asked how archival were these labels, I finally heard back from Epson.
" I wanted to let you know that our black-on-white products are now PAT (Photographic Activity) safe. This product has passed ISO Standard 18916, commonly known as the Photographic Activity Test, the international standard for evaluating whether materials are safe from potentially harmful chemical reactions during archival preservation, especially for photographic materials."
Hope this helps.
