Changes in CUPS v1.1.21:
- The scheduler did not separate Digest authentication parameters with commas (Issue #882)
- Fixed some problems with image printing to custom page sizes (Issue #891)
- Removed the remaining scheduler code that did not use the "close-on-exec" file descriptor flag to speed up program invocations (Issue #890)
- The "lpr -r" command removed the print file even if it was not printed. It now only removes the file if the job is successfully created (Issue #886)
- Revamped the custom page size orientation fix (Issue #127)
- The lp, lpq, lpr, and lpstat commands now report when an environment variable is pointing to a non-existent printer instead of just saying "no default destination" (Issue #879)
- Queue names with 2 periods (e.g. "printer..2") were not supported (Issue #866)
