Security flaws with printers

Interestng article, basically goes over flaws with PJL PCL and UEL.  It really affects  HP printers, not so much other brands since they do not support those protocols as extensively as HP does.  And these issues have cropped up before (I remember a tool called HiJetter several years back thtat mucked around with PJL and HP printers).
