I am trying to write a good one-liner for removing all restrictions on printing for Mac OS X 10.5. I had thought that [`sed`][sed] would be perfect for this, but I can’t arrive at a simple syntax for appending new lines that works well when pasted into a terminal window. Here’s what I ended up with:

perl -p -0 -i ‘.bak’ -e ‘s/(Policy default).*(Policy)/$1>\n\nOrder deny,allow\nAllow from all\n<\/Limit>\n<$2/s' /private/etc/cups/cupsd.conf Rather brutal, it just guts the default policy and replaces it with the following:

Order deny,allow
Allow from all

Greg Neagle has [a useful article about printing in the enterprise][mactech]. Apple suggests [adding the network group to the local lpadmin group][ht3511], but points out that mobile users would need to be added individually. In my case most accounts are mobile accounts and we trust everyone to manage print queues on a Mac, so removing all restrictions is acceptable.
