LPrint v1.0b2 January 26, 2020

This is the second beta release of LPrint, a Label Printer Application for macOS® and Linux®. Changes include:

• Added support for authentication of remote administrative requests (Issue #1)
• Added support for managing printers via web browser (Issue #1)
• The add, default, delete, and modify sub-commands now support the “-u” option (Issue #1)
• Fixed an ASLR issue with some Linux compilers (Issue #5)
• Added code to detach the Linux usblp kernel driver since apparently there are still Linux distributions shipping the old (and broken) usblp kernel driver (Issue #7)
• Device errors are now logged to stderr (for lprint devices) or the server log (for lprint server) so that it is possible to see permission and other access errors (Issue #8)
• Job attributes are now validated properly against the driver attributes (Issue #9)
• Fixed an issue in server mode - a failed IPv6 listener would prevent the server from starting (Issue #12)
• Added a “spool-directory” option for the server sub-command.
• Added a spec file for building RPMs.

Enjoy!

Thoughts on Leaving Apple... December 20, 2019

So today was my last day at Apple. Apple has been a great company to work for and I’m grateful for my time there. I accomplished most of the things I’d hoped for, particularly getting solid Internet Printing Protocol support in almost all network and USB printers sold over the last 10 years. I chaired the Printer Working Group for about half of my time at Apple, met and worked with a lot of really talented and considerate people, and mentored a few young engineers that have either excelled within Apple or moved on to their next challenges.

Going forward I’ll be taking a little time to reboot and start a new company with my amazing wife. I’ve missed working with her every day these last 13 years and I’m really excited to see where our new journey will take us.
