Actually, I was gonna say earlier in the thread, that back in the day MS label printing could look a bit crappy, like it was done on a printer, rather than production printed... and this was from disks I got in a full package with all the paperwork certificates and holograms etc circa 1993.
Edit: Just thinking though, there were several standards of "genuine" MSDOS disks, the retail, off the shelf version, and the OEM packaged versions. It's possible that MS gave the license but the OEMs actually had the install media produced themselves... As became increasingly common with later OS.
Was just looking at the print "quality" of the labels my pharmacist uses, and that label printer makes exactly the same jaggies and faint spots etc as I remember on MSDOS disk labels I believed genuine in 1993. I know I had an OEM package, but not sure of the original OEM as they were bought as surplus. Possibly Viglen or Elonex.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
