Decode an HP -GL/2 string

[webrabbit]

While decoding a PCL file, I encountered the following string:

[esc] %BWUAC14,4SP1PP1PW0TD1IWSC0,1.6932,0,-1.6932,2RO0IR0,100,0,100

I know the [esc] %B means to enter HP-GL/2 mode. Does anyone know what the rest of it means?

Brief analysis; it tells you what the commands are, but you'd still need the HP-GL/2 manual (part of the PCL5 Technical Reference manual) to decipher exactly what the parameters mean:

You can do this analysis yourself, using the PRN File Analyse tool in the free PCL Paraphernalia application, available via

Having said that, your code snippet revealed a bug in the tool, so I had to add in a few PCL sequences at the end to get it to describe the last HP-GL/2 command correctly.
