From: N_Cook on 21 Feb 2010 07:44 HP Laserjet 1020 I cannot find any way of getting that info from the ROM or wherever, no buttons at all on this printer. I have worked out a way of adding one , mechanically, the "milometer" section cut off an impulse counter and string connecting the trigger bar to a convenient solenoid that activates once a page. But before doing so wondered if anyone knew what driver file or whatever to interrogate . Is there a www site giving the empty cartridge weights of various printers, this one , I'm told nearly new cartridge Q2612A 12A is 611 grams

Have you printed every variety of test page? Some brands of printer add the total number of pages printed to at least one of their test prints. -- Don Phillipson Carlsbad Springs (Ottawa, Canada)

Prints a listing of files with appended numbers that stay the same regardless of how many print-offs of the test page. In the process of adding a mechanical page counter, plenty of space inside end cover, cutting a viewing port in that plastic end cover. Cut the milometer section 48x22x30mm off the solenoid part of an impulse counter. Hole through side to take some radio tuner dial cord to a PTO solenoid or whatever engages once per sheet delivery. Cut a slot and some more shaping to a nylon rod to extend the action out by gluing to the pole piece and then the cord glued to that with a spring and adjuster in the cord. Other end of cord glued part way along the ratchet arm for about same actuating movement there and the solenoid. Just got to fit it all in place and adjust, hopefully the extra loading on the solenoid will not disable it

Hi! > HP Laserjet 1020 > I cannot find any way of getting that info from the ROM or > wherever, no buttons at all on this printer. There probably isn't one. The LaserJet 1020 is a "dumb" printer despite HP's claim that it has a 234MHz "processor". I would practically guarantee that any such processor is only capable of processing data that has already been spooled into some proprietary printer language by the computer, and that it may even require its firmware to be downloaded by the computer before it can process anything. The printer may have no idea how many pages it has run. If you were to find an HP LaserJet 1012 or 1015, those printers do have onboard intelligence, accept conventional PCL input and the panel buttons can be used to produce a page count. William |
