Unpacking HP Printer Firmware Updates, Part 2 (jsof-tech.com)

Wouldn't be bad to have the word "printer" in the title here, HP makes or has made a laundry-list of different hardware.

Although now I wonder, how much might different divisions of a megacorp have their own firmware packing procedures, or do they try to unify? Hmm.


Ok, we've put printers up there.

Hey, cool stuff -I think these are the same people in defcon: https://www.blackhat.com/us-20/briefings/schedule/#hacking-t...

Reading part 1&2 I wonder how many people at HP tried to simplify that process and juste gave up.

It's probably pretty invisible for the developer if he has the "firmware creation pipeline" working on his machine but that's layer over layers of legacy stuff and the added complexity probably led to some nasty bugs.


Cool post, but I don't think this is really a "Show HN";

This isn't a Show HN, it's "just" a blog post.


Thanks! We've taken that out of the title now.

Also, please don't put things like "Part 2 in the series is up" in the title when submitting an article. HN readers are not fond of marketing noise, and the site guidelines ask you to use the original title, except when it is misleading or linkbait.

Also, it's generally not good for HN to split blog posts into series, let alone 4 part series. The later parts rarely get as much attention as the earlier ones, and we penalize follow-up submissions because they are repetitive: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que....


Thank you for the feeback and guidelines! We understand, respect and share the deep dislike for any marketing noise. In this case we do believe that each post in the series is a stand-alone post with its own clear value to the community.

We will refrain from sharing the next parts in the series, and come back to share the full series when completed.
