System log help?

Running 10.6.8 on an iMac (2.4 GHz Intel Core 2 Duo - Early 2008)

I was having problems with Dashboard, couldn't delete or otherwise
manage widgets (problem since resolved with restart). As part of
investigating the problem I looked at the system logs and noted the
following three lines that repeat every 10 seconds for pages and pages.

================================================== ================
8/19/12 1:36:23 PM com.apple.launchd.peruser.503[839]
(com.hp.devicemonitor[965]) posix_spawn("/Library/Printers/hp/hpio/HP
Device Monitor.app/Contents/MacOS/HP Device Monitor", ...): No such file
or directory
8/19/12 1:36:23 PM com.apple.launchd.peruser.503[839]
(com.hp.devicemonitor[965]) Exited with exit code: 1
8/19/12 1:36:23 PM com.apple.launchd.peruser.503[839]
(com.hp.devicemonitor) Throttling respawn: Will start in 10 seconds
================================================== ================

I looked in /Library/Printers/hp/hpio and there is no "HP Device
Monitor.app" in there, only an alias to "HPIOPrinterClassDriver.plugin"

I looked in com.apple.launchd.peruser.503, but the only thing in there
is a pref file called "overrides.plist" that appears to be empty.

I thought the HP Printer Drivers might need updating so I downloaded and
installed "HP Printer Drivers v.2.10 OS X" from Apple support. I'm still
getting the same three lines every 10 seconds in the system logs and
still no "HP Device Monitor.app" in /Library/Printers/hp/hpio

Printing to my HP Deskjet 3050A works fine, both before and after
installing the new printer drivers.

I searched the computer for "HP Device Monitor" and found an installer
package with that name in /Library/Receipts that appears to date from
Jan 24, 2012. I tried to run that, but get an error reading the
package, "The selected package is only a receipt."

Obviously, I'm in way over my head and just flailing about. Any help
would be greatly appreciated.

You've got some cruft leftover from some install of the HP printers. My
guess is it's a plist file in ~/Library/LauchAgents,
/Library/LaunchDaemons/ or /Library/LaunchAgents/

If this is way beyond the scope of you going to the Terminal.app,
finding the file, and deleting it, you should call AppleCare support and
they'll walk you through the problem. If you don't have support, take
your system into your nearest Apple Genius Bar and have them fix it. Or
just live it it. It's not hurting anything other than making your
system.log file bigger.

In terminal:

man launchctl

At the bottom, it lists the directories/folders where the various
launchd plists are stored. Each .plist file is normally for one job.

in this case, you could be looking for com.hp.devicemonitor.plist

you can also

launchctl list | grep hp

This should give you the names of all of the jobs with "hp" in it.

If you are willing to reboot, removing the offending files from one of
the directories listed in man launchctl and rebooting will fix it.

Or you can use launchctl stop and launchctl unload first to stop the
currently running job, and then delete the files. This avoids avoiding
to reboot.


To perform actions with launchctl, you may need to prefix with "sudo"
(but list works without it).


You can also use the Property List Editor (gone after Snow Leopard) to
edit the offending .plist and set the "Disabled flag" which will cause
launchd to ignore that .plist ( man launchd.plist to see the
documentation on the structure and options of launchd files)

Thanks for you help, Michael and JF. I do some very limited things in
terminal when I have very specific step-by-step instructions, but I
don't feel comfortable poking around in there otherwise. I'll probably
take the Genius Bar route since Applecare has long expired on this
machine. I wouldn't bother doing anything except for the fact that these
entries crowd out everything else in the system log.

Step by step (and copy paste friendly)

1. Open Terminal
2. type

launchctl list | grep ".hp."

You will get a list (possibly of one) looking something like this:

7245 - com.hp.print.deviceManager

(or something, it doesn't matter what it says)

3. double click the name part and copy it (command-c) and type

mdfind -name

and then press command-v and type

| grep plist

The | is important. You will get back a path something like

/Library/LaunchDaemons/com.hp.print.deviceManager.plist

4. copy and paste the whole line and type

launchctl unload

and press command-v

5. type in

sudo rm

and press command-v

6. Type in your password.

If you found multiple items in step 2, you will need to repeat steps 3-5
for each item.

The "." characters should be escaped as "\." since the stand-alone "."
represents any character.
