How to Bypass HP Cartridge Protection on Windows (LaserJet P1102)

-

If your HP LaserJet P1102 prints perfectly on Linux but outright refuses to print on Windows because of an "unofficial" toner cartridge, the hardware is not the problem. The issue is HP's status monitor software actively blocking the print spooler in Windows.

While you could theoretically bypass this by routing a Linux CUPS server through WSL, there is a much cleaner native solution: strip away HP's bloatware and install the raw, host-based .inf driver directly.

Here is the exact procedure to revive your printer.

1. Extract the Raw Driver

HP often hides basic drivers behind their "HP Smart" app. We need the raw files.

  • Disconnect the printer's USB cable from your PC.
  • Go to the HP support site, manually change the OS version to Windows 10 (64-bit), and download the full software package (.exe).

  • Do not execute the file. Running it will install the HP cartridge-monitoring software.

  • Right-click the .exe file and use 7-Zip or WinRAR to Extract its contents into a new folder.
  • Look inside the extracted folder for the core driver dictionary, usually named HP1100.INF.

    2. Force a Clean Installation

    Now, feed these raw instructions to Windows without launching any HP executable.

    • Open Device Manager, click on your computer's name at the top of the tree, and select Action > Add legacy hardware.
    • Choose Install the hardware that I manually select from a list (Advanced).

    • Select Printers, leave the default port (LPT1) selected for now, and click Have Disk....

    • Browse to your extracted folder, select the HP1100.INF file, and choose the HP LaserJet Professional P1102.
    • Crucially, if Windows prompts you, choose to Replace the current driver. This wipes the old HP monitor cache from the system.

      3. Re-route the USB Port

      • Finish the wizard and plug the printer's USB cable back in.
      • Send a test print. If the document gets stuck with an "Error" status, Windows failed to map the port automatically.

      • Cancel the stuck document, then open Printer Properties (not preferences).

      • Go to the Ports tab, scroll down, and check the box for USB001 (Virtual printer port for USB).
      • Click Apply.
        By forcing Windows to use the pure .inf file, your PC communicates directly with the hardware, bypassing the DRM loop entirely. Just remember to permanently avoid "HP Smart" and ignore any future firmware update prompts.

        VFD control with Arduino using RS485 link

        -

        Variable Frequency Drives ( VFD ) allow the control of spindles so speed can accurately be controlled and a detailed acceleration profile for the spindle and reverse rotation can all be handled. In essence a VFD is an three phase inverter for three-phase AC motor. I am using a popular (I mean cheap) Chinese VFD and though the reference manual is not great, I could see there is a built-in RS-485 port. I usually control the start, stop and speed selection using the keyboard on the unit but I thought it will be more useful if I could control everything from the same Arduino is doing our CNC table control. Some cheap RS-485 off eBay and some lines of code later, I can start, stop and change the speed from an Arduino. What a cool thing to have! Some configuration of your VFD are needed before you can use it like that.  You need to set PD163=1 (I am using address 1 in the code). PD=164=1 (for setting serial to 9600bps) and PD165=0 (for using ASCII and 8N1 character for...

        Arduino mood light

        I recently saw the cool mood lamp by Philips and I liked it. What I did not like was the price. I set myself to discover what the industry has to offer in terms of high-power LEDs. It turns out that since the old 20mA red LEDs the market has evolved in such a way that it seems the light appliances of the future might be completely LED-powered. Now there are 3W and 10W LEDs available. Either monochrome or RGB. I like LEDs as they last forever (I've never seen a LED that stopped working unless it was due to a current overload). High power LEDs are not cheap but they are very easy to control from a micro-controller using PWM (Pulse Width Modulation). They need DC low voltage power sources. I did a test with an Arduino board and a protoboard with a ULN2003 that I've used to control a 3W RGB LED . I programmed a never ending random sequence and this is the source code . Just connect each led (R,G,B) to the outputs 9,10 and 11 of the Arduino. If you need more current then use a Darl...

        4xiDraw: Another pen plotter

        -
        Image
        After watching a video of a new pen plotter made by Evil Mad Scientist we wanted to have a similar device. And having a 3D printer at hand plus some CAD software like Onshape or Fusion 360 it was a good exercise to design the whole thing. As usual the process was not completely straightforward, as initially it was more about copying the model we saw but as things were coming together some new ideas were explored. So while the first mock-up was based entirely on laser-cut parts (some of them glued together to make them thicker as the crappy laser I have access to is really depth limited as it is low-power).  Why laser-cut? Well because it was faster (or so it was supposed, but don't get me started on that). Once the first model was put together several ideas pop up: First, motors are in the way of carriage motion and reduce a bit carriage travel along smooth rods. Second, motors require another part that could be fused with the machine feet and rods support. Third, t...
