Question: Regarding cups API functions for cups standard/common options.

[ayush268]

Is there a way (function) in the cups API to get supported/default values for cups standard/common options e.g. page-border ?
Also how can we get the options shown by doing lpoptions via cups API functions, passing option_name as "job-creation-attributes" to cupsFindDestSupported does not give me all the options.

What version of CUPS are you using?

WRT things like "page-border", the list of supported values has been unchanged for over 15 years (last changes early in CUPS 1.1.x development) and so can be considered static. We can look at providing a page-border-supported attribute but it won't help you today...

What printing options are not listed in the "job-creation-attributes-supported" attribute?

[ayush268]

The CUPS version is 2.2.7.
The printing options that are not listed in the "job-creation-attributes" -> collate, fit-to-page, mirror, number-up-layout, outputorder, page-border. (these are lp common options.)

I tried using these options with lp command and they were working fine. I was thinking why these options were not included as "job-creation-attributes-supported" because they work for files of all types.

Of those options, only number-up-layout and page-border are generally supported for documents (but not for images). Of the rest:

• collate is a PPD option. The multiple-document-handling option/attribute is the proper replacement for copy collation, with separate-documents-uncollated-copies for uncollated copies and separate-documents-collated-copies, single-document, or single-document-new-page for collated copies.
• fit-to-page is deprecated in favor of the print-scaling option/attribute.
• mirror is a PPD option. There is currently no generic replacement (but there are some possibilities).
• outputorder is a PPD option. The page-delivery option/attribute (values same-order or reverse-order) is the correct IPP replacement but is not yet supported by the cups-filters project (I am looking at changed in cupsd to do a mapping at print-time...)

The page-delivery option/attribute (values same-order or reverse-order) is supported by cups-filters (in the pdftopdf filter now (version 1.20.4 which I released some days ago).
