Re: hplip-printer-app hangs and oddities (Re: Cups automatic duplex printing problems)

Hi list,

I'm replying to a very old message of mine. I tried to fix 
ttps://github.com/OpenPrinting/hplip-printer-app/issues/17 because I 
like my postscript printers to actually print postscript. Yes, I'm that 
kind of nerd.

Anyway, I sort of fixed the bug but I don't know why. So it's probably 
rubbish that I made, I just don't grasp the code path here.

I switched the last two lines of ppdEmitJCL() and suddenly

But this code has been there for ages. Has postscript with PJL been 
broken since 2014? I can't imagine that.

Would anyone please know why a normal Postscript printer with a PJL 
definition in its PPD file
*JCLToPSInterpreter: "@PJL ENTER LANGUAGE = PostScript <0A>"
... would print %%@PJL ENTER LANGUAGE (with two extra %% signs)?

Sorry for the voodoo code (semi-randomly switching two lines of code). 
With printers, I just cannot seem to avoid it :-(

Best regards,

Valentijn
