Bug Description
I have a problem with non-PPD options set in /etc/cups/
For filters and cups-browsed I have defined some options for being
stored in /etc/cups/
I set these options via
lpadmin -p <printer> -o <option>
getting a line
Option <option> <value>
in the entry of <printer>. What works is that these options get supplied
with every job, so I can use such options to configure filters or to get
filters into a debug mode. I am using this successfully for example with
the "usb" CUPS backend to find quirk rules for broken USB printers.
Now I also want to use this simply to mark print queues (setting an
option which is ignored by all filters). For example all queues created
by cups-browsed get the cups-browsed Boolean option set by doing the IPP
equivalent of:
lpadmin -p <printer> -o cups-browsed-
resulting in a line
Option cups-browsed true
in /etc/cups/
closed cleanly (system crash) and so did not remove the queues it
created in the next session finds these queues and treats them
correctly, so that crashes do not lead to ghost queues.
Now it seems that I cannot read out this option setting (without sending
a job and checking error_log), as
lpoptions -p <printer>
does not list the option (as "cups-browsed" or "cups-browsed=
val = cupsGetOption(
in a C program (with dest being the record of the printer in question)
gives val = NULL as one gets when requesting the value of a non-existing
option.
In CUPS 1.5.x (Ubuntu Precise, 12.04 LTS) this still worked. both
cups-browsed was able to read out the "cups-browsed" marker option from
its queues via the C line shown above and
lpoptions -p <printer>
contains "cups-browsed=true" in its output.
I have reported this bug upstream (Apple bug <rdar:/
Patch applies only to CUPS 1.7.x, not 1.6.x.
