cups.tczl posted

As something of a test, a start-up script has been added to start the cups daemon when the extension is loaded. This will only work if the following extensions are loaded in the following order:

expat2.tczl
dbus.tczl
libcups.tczl
cups.tczl

Note:
1. For versions of tc earlier than 2.4rc1, if the above extensions are placed in /tce, the dbus and cups daemons will not start on boot as the boot process loads the extensions in alphabetical order.
2. If the above extensions and cups.tczl.dep are placed in /tce/optional (or any other folder) and the appbrowser is used to load cups.tczl, then the dbus and cups daemons will start.

Note also:
The cups.tcel extension has not been modified.

perthie:
How should this work in 2.4rc1? When I try to add a printer, the Add Printer dialog is duplicated on the web page and the top half is hung up with "Looking for Printers...".

Juanito:
What kind of printer are you using - usb, parallel, network connected?

I tested with two different hp usb printers via hplip and the printers were found automatically. If you go to the next screen, you can enter a uri manually.

perthie:
I have both a local USB printer and a networked printer. CUPS 1.4 can't detect either, while 1.3.8 detects and sets up both.  When I manually set up the networked printer and try a test page, it comes out blank. This is a clean install of TC 2.4rc1 with the extensions loading into RAM. I can see the dbus daemon running.

BTW, Ghostscript is not listed as a dependency.

I brought cups.1.3.8 over from TC 2.3.1 and it works fine.

perthie:
Correction: The network printer was detected. The hangup seems to be with finding USB devices.

Also, the folder /usr/local/lib/cups has been given tc:staff ownership.  CUPS 1.4 complains if the printer filters are not owned by root.
