I did find out from the HP LJ4050 manual that its fuser operates at 400F (205C), so not too much above where my laminator works.

Oh bother! I really don't want to have to buy another laser printer! Does anyone know if there is a lower melting point toner (another brand perhaps) that will work with the HP 4000 series LaserJets?
Either that or I will need to make modifications to the laminator to increase its temperature range, proably a PID
Thanks
Dave

I tried our newer HP laserjet printer at work and its a no go getting the toner to stick well. Gave up and used our newer Canon instead ..
