Hi,
I have released cups-filters 1.28.17 now, with the following changes:
- libcupsfilters: In PPD generator create only one *cupsFilter2:
line for raster. Only use the most desirable/reliable format,
usually Apple Raster.
- libcupsfilters: In get_printer_attributes() poll
"media-col-database" separately if needed. On some printers
one gets "media-col-database" only this way. Often it reveals
important functionality, like for example borderless
printing.
- libcupsfilters: Let PPD generator also parse
"media-col-ready" IPP attribute. "media-col-ready" lists the
loaded media, in contrary to "media-ready", as list of
complete descriptions of the media ("media-col" data
structure). This often lists also variants like borderless
(it is the same physical paper). Especially useful when
"media-col-database" is not available.
- libcupsfilters: In generate_sizes() consider all margin
alternatives. When generating the PPD file for a driverless
printer, and in the media-{left,right,top,bottom}-margin-
supported printer IPP attributes there was more than 1 value,
the first value (which often was the 0 for borderless
printing) was not considered, leaving the borderless
functionality of many printers undiscovered (Issues #492).
Bug fix release, to more reliably discover all printer capablities from
driverless printers, especially borderless printing, and to preferably
use Apple Raster instead of PWG Raster or PCLM.
This is primarily for Bookworm as Bookworm will most probably not adopt
cups-filters 2.x.
Thanks in advance.
Till
