-> Just an update.  Some months ago, ( I think about 6 months ago) we had
-> a little thread here after I had successfully refilled the toner
-> cartridge on my little HP LaserJet 4L laser printer.
-> That "refill" is still working like a champ here, and if it is still
-> going strong after this toner is used up, I intend to refill it again,
-> and  - - so on, until it may finally give up.
-> Heck, this refill kit cost just $13 shipped, BIR, and that beats snot
-> out of Office Depot current pricing of $89 for a new HP toner cartridge,
-> and $56 for an Office Depot branded "remanufactured" one.

 Most I have talked to get 2 or 3 refills before the wear on the
Coated drum inside the cartridge starts to go bad. 
For non critical printing you may be able to stretchg that out quite a
bit.
