PRINTERS / TONER USED
  HP LaserJet 5L, original cartridge
  Samgsung 1710, cartr. refilled with recommended toner from TonerKits.com


  I made one print from each printer, on separate sheets from
the same package of Staples' paper, then measured:

   a) the minimum temperature at which I could smear the
      pattern with the iron (i.e., toner flows)
   b) the minimum temperature at which decorative foil
      would transfer to the toner (i.e., toner is 'tacky')

RESULTS
=======
		    HP LJ-5L		   Samsung
 toner		 99 C < t < 106 C	 98 C < t < 101 C
 smears		(210F < t < 222F)	(209F < t < 213F)

 foil		107 C < t < 112 C	 78 C < t < 83 C
 sticks/	(225F < t < 233F)	(172F < t < 181F)
 transfers

  Given the recommended fusing temps., I was surprised the
toner melting points were as low as they are.

  Best,
  James
