Where is the printer queue stored - and how to delete all queue jobs?

I ran into a problem after I installed the Roll paper feeder on my Epson R1800. All of a sudden files will not print anymore.

One thing that may cause a problem is that there are two previous files (pdf I think) that someone else tried to print yesterday looking for a different printer on regular Letter size paper that are still in the queue because they did not print successfully. Everytime I tell Photoshop to print my photo on the Roll paper, those two old jobs pop back up on the printer queue gui and the system stops saying "wrong paper type for this job". Then I delete those two old jobs so there is only the Roll paper one left but it just sits there and wont print. When I launch the utility to check is all is kosher, sometimes it will give me the ink cartridge levels without a problem but sometimes it claims a communication error. I have re-checked the connection and everything and all is OK. When I launch the printer utility and tell it to print a Nozzle Check test, it prints it without a problem so there really is no prob with the communication.

When I restart the computer and the printer and try again, the two old jobs that I deleted in the previous step always reappear. So I wonder if, those two pdf jobs are kinda screwing with the system and should be deleted. But as i said, everytime I delete them, they look like they disappear from the list but my photo job just sits there on the queue without printing. The jobs are not stopped and there is no Hold on this one. If I quit and re-launch the print job, the old ones re-appear in the queue. So they must be stored someplace and are not deleting correctly. Does anyone know where this cue file is stored and what it is called? I have looked in Application Support and in Preferences but I can't see anything that looks like it.

I have downloaded the drivers from Epson for this printer again but that doesn't do anything either. I am using 10.4.11 on an 24 inch iMac intel 2.4Ghz. I only use the stock Apple utilities, no funky third party addon except for the Epson drivers. The printer utilities are:

Epson Printer Utility v3.01
Stylus R1800 utility v4.7(161.10)

Thank you for any help.

I should add that if I remove the Roll paper feeder and try to print those two old jobs to get rid of them that way, it will say "Starting Job", the progress bar appears and the little diagonal bars across it are moving from left to right as if it was preparing the job, but it just stays like that and nothing else happens. So it really seems like these old pdfs are the problem. If only I could get rid of them....

It is unusual that the files keep reappearing, especially after restarting the Mac. For most local print queues, any job still in the queue would be deleted when the Mac is powered off. So, is the Epson using some sort of RIP software that could be keeping these two files? If so, there might be some other procedure required to flush the files.

Also, have you tried loading LTR paper into the printer to see if it will print these two files? This might be another way to clear the jobs.

BDAqua to the rescue ... once again! Well, sort of. Yes indeed they appear on that browser page. The not so good news is that when I hit Cancel Job or Release job on the right of the line listing the old job, I get the following error msg:

Error:
client-error-forbidden

No option as to how to fix unfortunately. I've tried from my account as well as from the admin account. Any thought on that one?

Thanks BD !

Hooray, we found the problem! BOO, we already found the problem elsewhere! 😉

Sooo, it seems we have some kind of Permission problem, have you Repaired Permissions ad rebooted?

At this point I think you should get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596

After installing, reboot holding down CMD+s, then when the DOS like prompt shows, type in...

applejack AUTO

Then let it do all 5 of it's things.

At least it'll eliminate some questions if it doesn't fix it.

The 5 things it does are...

Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.

First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! 🙂

Disconnect the USB cable from any UPS so the system doesn't shut down in the middle of the process.

Or we could maybe go back to that window, click on Printers, remove it? (Thinking perhaps the jobs will go away with the printer!?)

Or would you like to delve into the hidden folders/files to try to handle this?

To add to BD's excellent information, I did some testing and found that a Reset Printing System will also delete jobs held in the spooler. To get the job to stay in the spooler, I created an LPD printer that did not exist. So the scenario is not the same as your setup but it did clear the spool file, which resides in ./var/spool/cups. Note that this will remove the printer queue so it will need to be added again.
