[cups-devel] Using cups API to send PDF document without converting to PS first

[Nimesh Amin]

It seems like it's only passing through pdftopdf now, which is much
better.  However, I can't set options like I used to through cupAddOption.
Did the syntax change?  Previously, this worked (from CUPS website):
*OpenUI JCLPasscode/Key Code: PickOne
*OrderDependency: 10 JCLSetup *JCLPasscode
*DefaultJCLPasscode: None
*JCLPasscode None/No Code: ""
*JCLPasscode 1111: "@PJL SET PASSCODE = 1111<0A>"
*JCLPasscode 2222: "@PJL SET PASSCODE = 2222<0A>"
*JCLPasscode 3333: "@PJL SET PASSCODE = 3333<0A>"
*JCLCloseUI: *JCLPasscode
*CustomJCLPasscode True: "@PJL SET PASSCODE = "\1"<0A>"
*ParamCustomJCLPasscode Code/Key Code: 1 passcode 4 4

----- Then with CUPS API:
num_options = cupsAddOption("JCLPasscode", "Custom.7777", num_options,
&options);


Here are the filters in the generated PPD, below.  Oddly enough, adding a
printer directly produces this, but the auto-detected printer that was
added didn't have pwg-raster and made application/pdf weight 0.
*cupsFilter2: "image/urf image/urf 100 -"
*cupsFilter2: "image/pwg-raster image/pwg-raster 100 -"
*cupsFilter2: "image/jpeg image/jpeg 0 -"
*cupsFilter2: "application/vnd.cups-pdf application/pdf 10 -"
