Take a look at
tblCustDevPrinter. Fusers, maintenance kits, etc. are lumped in there with toner and ink, so you'll need to do a bit of filtering, but you should find what you need in that table.
If one of the existing printer consumables reports is close to what you're looking for, you should be able to use that as your base and just filter out toner, ink, thermals, etc.
If you want an idea what to filter for, this should get you going:
SELECT Distinct Tonername
FROM tblCustDevPrinter
WHERE
Tonername NOT LIKE '%toner%'
AND Tonername NOT LIKE '%cartridge%'
AND Tonername NOT LIKE '%ink%'
