wow ... i to think.. i just paid 90$ for a toner cartridge replacement for my HP laserjet 4 ....

..
wonder if those would work with the standard Laserjet 4 , i believe the model #'s are different then what mine were...

... still awsome price for toner cartridges...
lol. those laserjet 4 printers last forever... mine is from 1983.. put in a new cartridge and works perfect ...
