Indeed if they had the identification code they would have been able to pinpoint the model and serial number of the printer, but they haven't released that information -- only that it is a HP printer with HP 302 or 304 model ink cartridges, which I assume is based on analysis of the chemical composition of the ink.
- dhosek 4y agoThey also say, “Ink cartridge type HP 302 or HP 304 color cartridges are used.” [italics mine]. In that case, they may have the yellow watermark and just aren’t saying so.
- jcrawfordor 4y agoTo my knowledge only laser printers participate in the MIC scheme. While the boundaries of the program are somewhat unknown, just from a technical perspective inkjets generally struggle to produce low enough coverage for the marks to not be pretty visible to the eye (bleed of inkjet inks prevents high-pitch halftoning performed by laser printers to produce very low coverage).
