Bug Description

The permission on /var/spool/cups are wrong leading to errors such as this (from syslog):

/hpps: [5186]: error: Failed to create /var/spool/cups/tmp/.hplip

$ ls -alh /var/spool/ | grep cups
drwx--x--- 3 root lp 4.0K Aug 29 16:43 cups

The permissions remain incorrect after running hp-doctor/hp-check several times.

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the
proper dependencies are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied
tarball has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time
dependencies).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]

Hi Nathan,

Can you install the latest hplip-3.15.7 package ?
You can download hplip-3.15.7.run file from http://hplipopensource.com/hplip-web/gethplip.html and install the package by running command 'sh hplip-3.15.7.run' in terminal.

Delete the existing print queue for this printer using command 'hp-setup -r' and re-configure the new queue using command 'hp-setup'.

Let us know if the issue is still same..

Thanks,
Goutam

Hi,

I run into the same problem. I am using a fresh install of Kubuntu 15.10. I installed the latest version of the software (3.15.9) but permissions did not change. Once I run a chmod 777 command, I was able to set printers.

I saw this too.

I just did
sudo apt-get install hplip --reinstall

and it added /var/spool/cups/tmp/.hplip
with the correct permissions

$ sudo ls -alh /var/spool/cups/tmp
total 36K
drwxrwx--T 3 root lp 4.0K Nov 19 09:56 .

-rw------- 1 lp lp 0 Nov 19 08:34 cups-dbus-notifier-lockfile
drwxr-xr-x 2 lp lp 4.0K Nov 19 09:56 .hplip

might be a work around, don't know why it didn't do this before (or why it got deleted)

I encountered this too on Debian 8.2 Jessie, with HPLIP 3.15.11 from HP site and Device URI: hp:/net/HP_LaserJet_Pro_M201n?ip=192.168.1.129

Ocasionally printed pages will be incomplete, for example a spreadsheet has the whole grid, but some values are not printed.
The spool file (a PDF file in /var/spool/cups/d00553-001 for example) looks good, but the printed page doesn't. The HP tray icon says the printing was successful and doesn't display any errors.

Syslog has this entry though:

Dec 26 23:37:34 mama-tata-laptop hpps: [8238]: error: Failed to create /var/spool/cups/tmp/.hplip
Dec 26 23:37:34 mama-tata-laptop dbus[527]: [system] Activating service name='org.opensuse.CupsPkHelper.Mechanism' (using servicehelper)

Dec 26 23:40:26 mama-tata-laptop python: io/hpmud/hpmud.c 702: invalid channel_close state

If I retry printing (either from the application or just doing a 'Reprint job' from CUPS) will print the full, correct page, and then
/var/spool/cups/tmp/.hplip will exist with correct permissions.

Note that Debian uses systemd by default now, is this related to perhaps some race condition with its PrivateTmp feature https://bugzilla.redhat.com/show_bug.cgi?id=830630?
I've switched to SysVinit now, and will try to reproduce the problem.

FWIW I had a Samsung ML2010P and it never had problems like this: on rare ocassions when there was an error it'd print a postscript error mesage and CUPS would say printing failed, it didn't print half the content and claim it successfully printed the page.

The problem still happens with SysVinit and hplip 3.16.2, just got an incomplete print and this syslog message:
Feb 22 17:02:16 mama-tata-laptop hpps: [11414]: error: Failed to create /var/spool/cups/tmp/.hplip

If I look at the filesystem now the dir did get created:

I'm able to add HP printers and print, but I still get this error from journalctl -b

/hpfax[8399]: [8399]: error: Failed to create /var/spool/cups/tmp/.hplip

I ran hp-check and didn't get any errors or missing dependencies. I've tried renaming the .hplip folder, but when I reboot, the renamed folder is deleted and a new .hplip folder has been created. I've tried reinstalling hplip numerous times, along with removing and reinstalling my printers using hp-setup.

I've also checked the privileges, which look the same as what others have posted above:
$ sudo namei -l /var/spool/cups/tmp/.hplip
f: /var/spool/cups/tmp/.hplip
drwxr-xr-x root root /
drwxr-xr-x root root var
drwxr-xr-x root root spool
drwx--x--- root lp cups
drwxrwx--T root lp tmp
drwxr-xr-x lp lp .hplip

Please let me know if there's anything I haven't tried, or if there is a solution.
