Only root can print

--------------------------------------------------------------------------------

Hi, I have this strange problem. Only root users can print, normal users cannot and no errors are shown, the command is just ignored. I am sure its a problem with rights but dont know where....I hope you can help, thanks.

Is this printing from command line or from within an application? New server or just new problem? What's the OS AND version?

You state no error are shown - have you looked in your messages file or just stating "no errors are shown ON SCREEN WHEN normal users attempt to print"?

Check your lp binaries - if they have the wrong ownership or permissions, ordinary users won't be able to print.
Check your /tmp directory permissions - known issue of some 3rd party apps changing permissions on /tmp and then folks can no longer print.
Check permissions on /usr/spool/lp and/or /var/spool/lp

Please post back with the requested information or your solution if found.

from an application, I havnt yet tried from the command prompt. New problem, I am using SCO OpenServer 5.0.6.

Have not checked the messages file, but no errors are shown on the user screen and either on the console screen. Also there is no job in the printer queue.

What must the persmissions be on the lp binaries?

Thanks for helping..

Is this a local printer (attached to the SCO server) or a network printer?

If it's a network printer, first check the permission on /etc/hosts:
See SCO - Non-root users are unable to print to (JetDirect) network printers

And since I can't seem to find the right information:
SCO - printing a file - this should assist somewhat.

its a local printer connected directly to the server via a serial DigiBoard.

I will try this printing to a file bit to see what happens.

NAME

SYNOPSIS

PARAMETERS

	      thread	The thread whose scheduling priority is to be set.

	      prio	The new priority for the thread.

DESCRIPTION

       The function sets the scheduling priority of thread to the value prio.  If the function fails, the scheduling priority of the target thread

	      The value of   prio is invalid for the scheduling policy of the specified thread.

	      The implementation does not allow the application to modify the priority
			     to the value specified.
