    [lots snipped]

    I examined some prints last night and also couldn't find any yellow
    dots. Brain function returned this morning when I realized that I was >>looking at B&W prints from my monochrome laser printer.

    I have days like that too. As long as it's not weeks, I'm not too
    worried.

    here's an old series of articles by the kind folk at EFF
    describing the issue.

    I probably have read that long ago.

    Hum. Is this an USA thing? I think the EU privacy laws should make this
    illegal in the EU.

    I found very little on the topic for UK or EU printers:

    "Why printers add secret tracking dots" (Jun 3, 2020) <https://www.bbc.com/future/article/20170607-why-printers-add-secret-tracking-dots>

    "German researchers defeat printers' doc-tracking dots" (Jun 27, 2018) <https://www.theregister.com/2018/06/27/german_researchers_defeat_printer_tracking_dots/>
