Description of problem:
While printing, I attempted to change the printer configuration via
printman. This returns an erroneous message: "tray empty".

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Send a job to print, and *while the job is printing*
2. Start Print Manager
3. Try changing the printer, and / or printer options

Actual Results:  Printman reports "tray empty!"

Expected Results:  Printman should say: "printer IN USE"

Additional info:

If this message is sent from a remote printer (mine is local),
it would be "mis-informative".

This message originates in CUPS.  I've seen it too actually.

Comment 2 Tim Waugh 2003-03-07 21:32:33 UTC
USB printer?  Now that I look this seems to be due to the kernel:

  if (ioctl(fd, LPGETSTATUS, &status) == 0)
    fprintf(stderr, "DEBUG: LPGETSTATUS returned a port status of %02X...\n",
    if (status & LP_NOPA)
      fputs("WARNING: Media tray empty!\n", stderr);
    else if (status & LP_ERR)
      fputs("WARNING: Printer fault!\n", stderr);
    else if (status & LP_OFFL)
      fputs("WARNING: Printer off-line.\n", stderr);

So perhaps the kernel is returning the wrong values?

I've seen this message with a USB-connected HP DeskJet 990C.  What printer are
you using, and with what connection?

Comment 3 Elton Woo 2003-03-07 22:00:38 UTC
I am using a Lexmark Z53 connected via an Atmel 4-port USB hub. Default kernel 
is kernel-2.4.20-2.48 and I am currently logged in using kernel-2.4.20-2.54. The problem 
occurs with either kernel. I keep switching between these kernels due to ongoing problems 
with CD burning. 

Comment 4 Tim Waugh 2003-05-28 09:30:15 UTC
Think this might be fixed in CUPS 1.1.19.

Comment 5 Elton Woo 2003-05-28 15:44:07 UTC
now the Printer Configuration app (print manager) just hangs with the message: 
"Loading printer information, Please wait..." (and wait, and wait, and *wait*.....).  
I'm forced to kill the print manager session. This happens either when loading 
_during_ a print job, or without any print job in the queue. 
kernel-2.4.20-9.athlon.rpm in now the default, with the following package 

Comment 6 Tim Waugh 2003-05-28 16:38:14 UTC
What version of redhat-config-printer?  Run it from the command line.

Comment 7 Elton Woo 2003-05-29 19:26:28 UTC
I did a clean reinstall of the sytem, and print configuration works ok now with 
redhat-config-printer-0.6.47-1, cups-libs-1.1.17-13, cups-1.1.17-13. The sluggishness 
may have been caused by other packages that I had installed from rawhide. (...sorry about
