CentOS 5 :: Printer In GUI Can Print Fine From The Command Line
Oct 6, 2009
I work at The University of Alabama as a sysadmin on various HPC resources and also provide support for faculty using Unix systems. I've run into one problem that is affecting two different desktop systems running CentOS 5.3.oth of these systems have the latest updates. These machines have standard network-attached printers. One is an HP LaserJet 3250 and the other is a model that is pretty close to that one.Previously these users were able to print from graphical applications such as Firefox, but now when the print dialog is opened on ANY graphical application, it causes a hard freeze on that particular app.Printing from the commandline via `lpr` gives no issues and test pages from the Printer Admin interface also succeed.This problem has me stumped, so I'm looking for any insight as to what could have changed. I do not know what changed between the time when the printers worked graphically and when they stopped, but the users assure that they have changed no settings. The only thing I can suspect is a rogue update since this is affecting separate users on separate machines with separate printers.
I'm from a Solaris (printer.conf) background and having trouble setting up a printer on the network. My CentOS box does not have a GUI interface available. I have been playing with lpadmin trying to add a printer - which it did, but everything is disabled, and the "enable" command is not found on my machine.
How do I make a simple printer on my network talk to my centOS box?
Here's the printer.conf from a Solaris machine that works:
raphael: :bsdaddr=igppps1,raphael,Solaris: And the printers.conf from the CentOS box: lumina# more printers.conf # Printer configuration file for CUPS v1.2.4
I just recently learned about the wonderful little lpr command- and using man -t (bash command) to beautifully print man pages for reference- but is there a way to print both sides of the paper using a printer so equipped?
I am trying to find a way to print PDFs from the command line. I was using "cups-pdf', but I want to be able to specify the output folder from the command line. Is there a way to do this? I guess what I am trying to do is the Gnome "Print to file" option in the terminal so I can easily print off a batch of file to whatever directory I wanted.
I am using an awk command to print a line from a cvs file.the awk command includes an if statement that filter the output-lets say i want to print all the lines that the price field is greater than 30.i have it working when i put the parameters myself.. but when i try to send them with vars it wont work..i am sending the sign of the if statement - can only be: == , < , >it looks like this:
We are running RHEL 5.1 on the 2.6.18.53 kernel. We are attempting to pass print jobs to a Lexmark printer with the lp -o landscape command. The print jobs continue to print "portrait". Is anyone aware of this issue and is there a work-around to get these print jobs to print in landscape format?
I have a requirement to print images (two to be precise) from the command line of a given size and without losing too much quality.
So, I may have two images, a.jpg and b.jpg which may be 4x4" and 6x4" respectively (the sizes may vary). I need to be able to print both these on a single sheet of paper (one under the other) at a given size for each - so a may be 2x2" and b may be 3x2" - the aspect ratio will always be maintained (or as near as possible!)
I am currently doing this a very messy way (because I don't know any other way!!) - basically I am converting the picture to a given size using a set density using convert and then concatenating the two using montage.
Here is part of my script:
Code:
Don't worry too much about the case statement at the end - that is just to be able to select to print either A, B or A and B.
The issue with this is that is doesn't work great if the aspect ratio is not maintained perfectly and also, it loses quite a lot of quality on the print.
I have a very old windows app which I wrote years back in VB (o dear! ) which does the same thing and the quality is fine (I am running it through wine). I want it to be command line though because I want to run it as part of other scripts etc.
CUPS was not originally installed on my server, I have installed it but cannot print to my network printer. On my laptop, I can... they are both running the same version of Debian. What could be missing?
Here are some details...
I have two computers running the same version of Debian. One is a server with no GUI and the other is my laptop with GDM installed. My laptop (which prints with no problem) is connected via Wifi. My server is connected directly to the router via Ethernet. I cannot print from the server.
The printer is a Canon Pixma MP495 that connects to the router via Wifi. I have downloaded drivers for the printer from [url] and installed them successfully using dpkg on both computers.
Right now I have a regular text file that I am using for a test page. To print from my laptop (with success) I type:
Code:
This does not work from the server. What could I be missing?
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.
CUPS error log: I [02/Apr/2009:00:03:45 +0300] Adding start banner page "none" to job 125. I [02/Apr/2009:00:03:45 +0300] Adding end banner page "none" to job 125.
My .jar file needs and uses some files in the same directory it's in (everything, including the jar was unzipped into said directory). It runs perfectly when I do java -jar file.jar in the command line, but there's trouble when I double-click the file when running from the file system manager. I've tried a custom command under properties ie java -jar, but the problem is that the .jar file doesn't seem to be able to use any of the files in the same directory. When running, the jar can't find any of the files that it needs.
I have printer in CUPS that due driver problems (hp 1010) form time to time goes into pause. I would like to write a shell script that will be once per hour resuming printer in cups.But I have no idea after googling for couple of minutes how to resume printer from shell command line.
My wife has a canon MP470 printer and running ubuntu 10.10. I am able to print black and white, but unable to print photos. I got it to work using another driver, but not the 'correct' one for this printer. I have searched a bit and don't see anything about ubuntu 10.10, just older versions. Or should I just network her to my printer....?
I am trying to write a program in C which compares two files and prints the line that is equal.
Here file1.txt has
and file2.txt has
Note: file2.txt consist of only a single string where as file2.txt has multiple lines. Actually im comparing two files with md5sum values.
Here is the code but it compares only first line of files..but it should compare the whole file1..and sorry iam a beginner in C can any1 sujest some modification to this code so that..it can compare file2 with entire file1
I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
[Code]....
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.
Anyone know why my fresh installation of centOS server is so slow? Seems like it takes over a minute to execute a command, im not doing anything complicated either. Secondly, how come at times when I type reboot the machine starts to beep, one long loud annoying beep.
Our one remaining problem seems to be printing. She has an HP OfficeJet 6500 USB printer. We have the computer conntected. Strangely, when I boot from the CD the printer shows up as installed even though I did nothing to install it. After having submitted a print job it shows the printer status as "idle" and the print queue is empty. I tried deleting that printer and re-installing. The installation went as one would expect. However the results are the same. I'm beginning to think that somehow the problem is related to the fact that we are operating from the live CD. getting this thing to print from the live CD.
I've written a script to parse a file and print each line that ends with matching pattern, if the next line is blank. The pattern lines are the result of md5sum $i|sed 's/path///g' so that only md5 and filename appear. Here's what I'm using.
Quote: for fline in `sed -n '/.*.ext$/p' file1` do if [ "`sed -n -e '/'"$fline"'/ {n; p;}' file1`" == "" ] then echo ""$fline" has no info" >>file2 fi done [Code]....
I have a perl/python interpreter available on the system so really as long as the script would run on a standard linux build I'll be happy.So I don't know how to program a script that would find the unique key (which if needed, can be easily stripped out and put into a separate file) and then print out the data below it without going into the other lines.
I'm using CentOS 5.4 x86_64 on my Dell Inspiron 1440. Is there any way I can get information about the battery(charge) through command line without X server.
I'm using several 3rd party repos for Centos - RPMforge, ATrpms, EPEL, REMI. Is there some way I can set the priorities for these repos in a bash script, using a YUM command? I cannot find anything in the YUM man page, or the yum-utils package.
Smart PM has a command to set channel priorities from the command line. Wondered if I can do the same for YUM repos?
Just got the new Dual Quad Server and after the installation was completed, It was the destkop edition... Can I get a reference on how to install the "Command Line Only" version of CentOS, OR Can I run the desktop edition and still be able to host VPS's and Web Servers, etc...
