[Python-apps-team] Bug#515184: pkpgcounter failes to read PJL[well, it's not PJL]-wrapped postscript

[SaGS]

Hi all,

I’m not a Debian user, but noticed the bug filed against Ghostscript and 
would like to make a comment and suggest another thing to try.

First, the sample file is *not* valid PJL+PostScript. The "!R! ... etc ... 
EXIT;" part is Kyocera's Prescribe. That's where the error comes from, as GS 
does not intrepret PRESCRIBE - as it does not interpret Epson's ESC/P and 
others.

Second, what I would like to suggest is to consider replacing the "!R! ... 
etc" with "@PJL COMMENT !R! ... etc". Then the file will be valid 
PJL+PostSCript, and there won't be any problems anymore. From what I 
understad from Kyocera's documentation, the "!R!" is recognized in any 
context, so I expect it has the desired effect even if "cloaked" inside a 
"@PJL COMMENT". Unfortunately, I don't have such a printer to check. And, 
where does this "!R!..." come from in the first place? Is it from a PPD? If 
yes, and my idea works, then this bug is very easy to fix by changing the 
PPD, without the need for an ugly workaround in Ghostscript.
