I remember having to debug the printing system (lpq, converters etc.) on my first Slackware system back in the early years of the second age, with plenty of shell scripts and literal postscript output. So I regard this with a certain amount of schadenfreude.<p>(Although the &quot;printer&quot; part of the headline makes this sound much more fancy and hardware-oriented than what it is, yet another HTTP-based protocol that&#x27;s parsed enough to work for a few use cases).
