Since my last server upgrade, last Thursday, cups is having a strange behavior: I have 3 text-only printers, and an application that prints to them. The application, to print 5 lines, it sends 5 jobs to the printer. Before the upgrade, all the jobs where printed sequentially, without any delay. After the upgrade, cups makes a small delay (5s or more) between every one...Its very annoying for the users...
View 1 RepliesI've set up a cups printing server using ubuntu 10.04.1 LTS. The printer's a HP Laser Jet 1018 I can connect to it over vpn using openvpn from my netbook which is also running ubuntu 10.04.1. I can connect to the printer all right and test page prints without a problem. But if I try to print anything else, it take at least 5 minutes before the job is successfully send and printed out.
Also, on the client side, for example, the file size would like 500k, and when it finally prints out, the file size on the server side is less than 10k. The file is a black and white document, and from what I can tell, the printed page is not missing any information.
I have a problem with cups dropping print jobs. The machine fedora 13 installation using cups 1.4.4-10
The dropped jobs happen only rarely happen and therefore is difficult to debug the problem since it doesn't happen 99% of the time. This morning (while in the shower) I wondered if the lost jobs are lost because they are timing out, perhaps because of slow input from a user. I can test this more later in the week..
The print jobs are initiated from within a COBOL program. COBOL opens the print file as output and at this stage a job appears in the print queue with a status in the print queue of "held".
The user types in various bits of information and when complete the program executes the final write to the output print file. The job is somehow released and then is physically printed by CUPS. I suspect that if the user is slow the "held" job times out and then the job is lost.
There are a number of timeout directives in cups.conf but I am unsure which might be appropriate in this case. Or perhaps there is some other timeout thing happening.
I've setup two printers through a system running Ubuntu server that are shared with 30-40 users on our school network.
If the printers run out of ink or paper, they stop printing. The lazier members of staff don't proceed to recharge the ink or paper so when somebody does, hours later, the old jobs start printing again which the teachers no longer need or want.
I'd like to automatically have my system purge print jobs older than 1 hour. I'm running CUPS and sharing the printers through SAMBA. How do I do this?
Not sure if this is hardware or software so I am raising the question here. I have an Ithaca 280 printer that worked great on fedora 8 with cups 1.3.3. When I upgraded my server and installed Fedora 12 with cups 1.4.2 i noticed a 5 second delay between sending a print job to the printer and it actually printing. This issue doesnt happen with laser printers, just the ithaca thermal printer. I have tested this with 10 other ithaca 280 printers and all of them have the same result. I am using a raw driver, and it is an IP based printer setup for Jetdirect in cups. The setup is identical on a Fedora 8 server as it is on this Fedora 12 server. I have even taken the steps to upgrade to cups 1.4.4 just to see if it was corrected in a newer version, but the issue is still there. I have a utility that writes the raw text directly to the printer which i used to test that it wasnt an issue with the printer or its internal print server. That utility allows the document to print immediately.
what is causing this delay and how to correct it? If not, does anyone know how to print directly to the printer using cups instead of letting it go to the queue first like cups normally does for print jobs?
I have a 11.3 machine as a print server sharing out a printer Then I have two clients using that printer. One 11.3 and one 11.4 6 of 6. When I print from LibreOffice on either machines every other print job disappears. I'm a bit puzzled ! It's not random it's exactly every other that doesn't show up at the server. It's not in the server job log.
View 5 Replies View RelatedI initially had a problem accessing the CUPS interface (see my other post) and got that resolved by adding the user "cupsys". Now, everything "looks" ok, and when I print a test page, it shows it as completed (in CUPS). However, the page never prints.
The printer is a Canon MP600 (using the canonmp600en.ppd file to configure it). Here's the output of my conf file.

I have a home Linux box with Mandriva 2007.1 and installed a Samsung ML-1210 I use it as a network printer. Sometimes the printer jams the paper and it won't print after it.
The situation is as follows: The paper gets jammed. I clear it and everything looks fine. When I want to print the print job stays in "processing" and the printer doesn't do anything. It doesn't matter if I send the job locally via VNC or from a remote machine with IPP or from a windows client with samba. The job is received, gets to the processing phase but nothing happens after that. It seems like if the printer wasn't connected. The only way I was able to solve this is to completely restart my Linux Box.
- Switching off/on the printer doesn't work.
- Plugging the USB cable in a different slot doesn't work either (I even replaced the USB cable)
- Restarting the CUPS and SAMBA server won't help
- Switching the printer offline/online in CUPS does nothing
- I tried to change "reprint after paper jam" and other settings, still doesn't work.
It looks like nothing helps, but after I restart the box, everything works again.
There's a line in the cups error log that is suspicious, but I don't know what to do with it:
SLPReg of "SAMSUNML1210" failed with status -20!
Not sure when CUPS started acting up. I have the latest 13.1 current software installed.The first page to print is always OK, but all succeeding pages are overwritten. The second page shows the first page on top of it, and the third shows the preceding pages on top of it - and so on. Has anyone else seen this problem?I guess the printer buffer is not getting flushed correctly. If my configurations were trashed in some way, I don't know where to look for a fix.
View 14 Replies View RelatedAfter GRUB 2 comes up (I'm running Ubuntu 10.10) and I choose the OS to boot, there is about a 5 second delay where nothing appears to happen after I make the selection -- no disk activity. It happens consistently every time I boot. Again, this is after I choose the OS to boot, so it shouldn't have anything to do with the standard delay to allow me to choose the appropriate OS.Is there a good way to troubleshoot this and determine what is causing the delay?

Basically when I boot the machine I first see the terminal login, then after a moment I get what looks like some graphical corruption followed by GDM appearing.
I've already attempted reinstalling GNOME and X, then manually reinstalling GDM, but none have solved the problem. I'm currently in the process of enabling boot logging as described in the thread, so I'll post that soon.
I am using centos 5 for squid. I have enabled delay pools in it. The scenario is I have two clients machines have IP address 192.168.1.200 (The Manager) and 192.168.1.201 (Manager Assistant). The issue is I assign 512kbps to the Manager IP address and 128 to his assistant. When either of them download it start from 60 KB/Sec they finally get 11 KB/Sec which is wrong. If I disable the assistant delay pools settings then the Manager get 60KB/Sec continuously. By enabling both squid does not show any error.
Following is my line of code taken from squid.conf
Code:
acl our_512kbps src "/usr/local/squid/etc/our_512kbps"
acl our_128kbps src "/usr/local/squid/etc/our_128kbps"

I have a Cent OS dedicated server, not sure what version though as I'm new to Linux. How do I find out what version I have? Is there an anti virus or security package that I can install on my server which can use Cron Jobs to do a scan every 12 hours.
View 7 Replies View RelatedI have install squid 2.6 in my cent os 5 system. The proxy server is working perfect using the following method.
Code:

I want to enable delay pools feature in it.For that purpose I do as following
Code:
[root@localhost squid-2.6.STATBLE22]# ./configure --enable-delay-pools && "configuration successful"
The question is should I configure it as I do it for squid
./configure --enable-delay-pools--prefix=/usr/local/squid
To enable delay pools may I need the correction in the steps which I have taken.
[root@localhost squid-2.6.STATBLE22]#make
[root@localhost squid-2.6.STATBLE22]# make install
In short to enable delay pools may I just use
# ./configure --enable-delay-pools
then
#make
#make install
We have a squid-proxy configured with 1 delay pool to limit the bandwith to 6M. I have to create a kind of exception for a specific

I am trying to get a printer hooked up to my server and am told i need CUPS installed. I have networking set up and the Centos 5 is a host to a Windows XP guest using VMware. I am trying to get the server to act as a print server and know next to nothing about Linux. Can anyone walk me through the process please? I have downloaded CUPS-1.4.1-source.tar.bz2 and CUPS-1.4.1-source.tar.gz but do not know how to install things on Centos (or anything but Windows). Any help will be appreciated. Thanks in advance.

How do I configure CUPS to print to PDF?
On a pc running Fedora4 with cups-1.1.23-15.4 , I have printers setup that can accept lp submitted jobs from other pcs, including windows pc on the LAN and a UNIX machine that is not on the lan.

no system default destination
recently i have upgraded my centos 5.0 or 5.1 installation using 'yum upgrade' to centos 5.4 since the upgrade I am unable to print any PDF files as landscape, they get printed but do not seem to be rotated and are aligned a little bit less than when using portrait (test using the GUI and LP)
when printing a text file in portrait and landscape everything goes well tested on labelprinter Brother QL-580N and tested on Samsung SCX-5530FN Laserprinter both using the network I already tried 'yum downgrade cups' this works but with no success
I just installed CentOS 5.3 on Compaq desktop PC with HP laser jet 2100 attached to parallel port. The PC is connected to LAN with 2 other PCs running Fedora. I configured the HP printer as a shared CUPS printer and I was able to detect the printer from the other PCs running Fedora but I can't print test page from the other PCs.
P.S. I opened up port 513 and 631 for both UDP and TCP on print server PC and cups-lpd service is running on it.
I have a printer configured on my Ubuntu server using CUPS amd made it available to the local network. The printer is recognized on my other Ubuntu machine without any problems.
But on my Suse laptop, the printer is not recognized. Using the YaST printer Configuations, I choose the option "Recieve Printer Information from Remote CUPS servers. But no printer is found.But... when I choose Do All Yout Printing Directly via One Remote CUPS server and enter the correct IP address (192.168.1.100), the printer is found andI am sure the printer info is broadcasted because it shows up on my second Ubuntu PC. But why is it not recognized by default on my Suse machine
I know this is listed somewhere but I cannot seem to find it -
How to I add a root users to access the 127.0.0.1:631 interface for CUPS?
Running: Ubuntu 10.10
I'm in a bind and I don't know how to get what I want. Nmap shows ipp running cups on port 631. Great, simple enough I uninstall cups, along with its dependencies. A new portscan reveals that the port is closed SUCCESS, but... Ubuntu Update Manager nags me @ every restart about the "important security" updates. I can't lock the version of cups in Synaptic, because cups is not installed! So you see I'm in a bind. If I have cups installed I have an open port, and if I uninstall cups the update manager nags me. What do I do? I've tried:
- stopping the cups service and issuing the chkconfig cups off command... (doesn't close the port)
- uninstalling cups... (update manager nags)
- fuser -k 631/tcp (great, but @ reboot the port is still open)
Please teach me how to close this port / stop this service / tell update manager to shove cups.....
cups does not start with the server. When I try to start from the terminal I get the error message
cupsd: Unable to read configuration file '/etc/cups/cupsd.conf' - exiting!
cupsd: Child exited with status 1!
The log files show nothing. cupsd.conf exists. It is user - root and group - root with permissions set at 0644.
My interpretation of this is that the program is not launching from either boot or terminal for a fundamental reason. I do not quite see what that reason is .
I've been trying to figure this out for longer than I care to admit. We upgraded our print server (sysadmin) to 64 bit lucid and that moved our cups server from 1.3.7 to 1.4.3. We have a remote server that is still 1.3.7 (printhost1) but version difference doesn't seem to be relevant to the problem.
If I'm on console on sysadmin and do an lpr to a printer on printhost1, everything is copacetic. However, If I'm on a host that specifies "ServerName sysadmin" in its "/etc/cups/client.conf" access_log on sysadmin shows:
172.16.10.52 - - [22/Mar/2011:11:11:40 -0500] "POST /printers/103_hp4250 HTTP/1.1" 200 306 Create-Job client-error-not-authorized
and error_log shows:
E [22/Mar/2011:11:11:40 -0500] Returning IPP client-error-not-authorized for Create-Job (ipp://localhost:631/printers/103_hp4250) from 172.16.10.52
We've been using this method of sharing printers between locations for years and years so it not working now is a surprise.
cupsd.conf on sysadmin looks like this and is as open as I can imagine:
ServerName sysadmin
ServerAlias *
ServerAdmin webmaster
FileDevice Yes
SystemGroup staff
LogLevel info
code....
Additional symptoms are that only printers locally defined on sysadmin show up when the client uses System>Administration>Printing in gnome. Same thing when you browse printers in windows on our samba domain controller that backends on CUPS.
I just know that it's something simple that's going to make me facepalm but I'm at a loss.
My setup is like this: i have a small office network and i bought yesterday a new multifunctional printer Samsung SCX-4521F. It is shared with samba and connected to the server with USB. In the network everyhing works well, users can log on to the domain, print from windows to the new shared Samsung printer and i even managed to enable network scannin. But when i try to print from MS DOS i wont get a single page. We have an accounting program in dos. All the other computers are XP Pro SP3. My server is running for 2 weeks the newest CentOS with all updates. I'v maped the network printer in windows witht the command "net use LPT1 \ServerSCX-4521F. I get a message that maping was completed succesfully. If i start a print job nothing happens. "Printing" or "warming up" flashes several times on the printer and thats it.

I am demo'ing Kubuntu 9.04 workstation to a customer. He has a CentOS 5.3 server (my doing). On it is our CUPS Network file server. Everyone (65 of them) print to our network printer through it using LPR/LPD (and sometimes Samba).
Problem: when Kubuntu's Print Configuration Tool went looking for printers, it found every network printer's IP address, but missed my CUPS printer server. What did I do wrong on one or both ends (I have control over both).
I have installed Slackware 13 on one of the hard disks of my computer in order that I can get it working properly before changing over from 12.2.
My main problem is that I cannot get CUPS to change from 'Letter', which I presume is an American size, to A4, has anyone else had experience of this problem?
Apologies if this was asked before -- I have googled the last bytes out of my Firefox but fail to find anything helpful. Here's my problem:I have a foomatic hpijs cups-driver for a HP Inkjet (Non-PS printer) installed. Printing from UNIX-hosts works. I have cups configured not to allow raw-printing (/etc/cups/mime.types: #application/octet-stream, /etc/cups/mime.convs: #application/octet-stream).I have now installed samba-printing, the cups PS-drivers plus the Windows PS-drivers are populated to /etc/samba/drivers/W32X86/ and get pushed to the WIN-Client.Problem is that when I print from a WINXP client, the printer outputs heaps of Postscript-text instead of my page.I have tried to debug this a bit but fail to find anything really useful. My observations so far:
- The samba-pushed HP_Photosmart_3300.ppd (in both /etc/samba/drivers/... and in the resulting dir on the WINXP client) reads:
*cupsFilter: "application/vnd.cups-postscript 0 foomatic-rip"
