Simple. Printers support PostScript which is an executable file format. And for some reasons some vendors like HP though it to be a good idea to add an instruction that allows to update the firmware.
- RBerenguel 13y agoAn instruction through PostScript? Keep in mind PostScript is interpreted, so adding an instruction to the interpreter to update the firmware is... Really stupid on their side
- sliverstorm 13y agoOn the other hand, also super nifty. You or I could probably figure out how to update a printer with snmp, but any idiot can update their printer if they just have to print this or that page.
- RBerenguel 13y agoPrinting a direct PS file is not straightforward in most (Windows, Mac) operating systems, since they convert it to PDF (Mac) or wonder what the hell it is (Win, at least last time I tried). But agree, nifty... And dangerous!
