I find a specification for PCL6 here:
https://www.undocprint.org/formats/page_description_languages/pcl_xl

According to the 2.0 spec, section 1.5 Pages:

> Pages have attributes that define and effect the real page received or viewed by

So it appears that setting the PAGESIZE may not cause a @PJL line
because it's not a global parameter but a per-page parameter. 
So, I suspect that the settings are being used, but you may be
looking in the wrong place to verify it.

On page 51, under the BeginPage operator there are 2 examples:

> Beginning a simple page.
>   ubyte ePortraitOrientation Orientation
>   ubyte eLetterPaper MediaSize
>   BeginPage

> Beginning a page printing on Executive sized paper with duplexing enabled.
>   ubyte ePortraitOrientation Orientation
>   ubyte eExecPaper MediaSize
>   ubyte eDuplexVerticalBinding DuplexPageMode
>   BeginPage

I'm not sure if these are always encoded as plain text, so it may
still to be difficult to search for and verify. But it appears to 
me that you should be looking for a MediaSize parameter to the
BeginPage operator.
