If printer doesn't print

If your printer doesn't print documents, you can try to diagnose and to solve the problem using the following recommendations.

1. Check if the printer is installed in your system

Run Configurator and switch to Printers tab in Printers configuration window to look at the list of available printers. Make sure that your printer is displayed there. If not, please, invoke Add new printer wizard to setup your device.

2. Check if the printer is started

Open Printers configuration and select your device in the printers list. Look at the description in Selected printer pane. If its status contains "(stopped)" string, please, press the Start button. After that normal operation of the printer should be restored. The "stopped" status might be activated when some problems in printing occurred. For instance, this could be an attempt to print document when MFP port is claimed by a scanning application.

3. Check if MFP port is not busy

Since functional components of MFP (printer and scanner) share the same I/O interface (MFP port), the situation of simultaneous access of different "consumer" application to the same MFP port is possible. To avoid possible conflicts, only one of them at a time is allowed to gain control over the device. The other "consumer" will encounter "device busy" response. You should open MFP ports configuration and select the port assigned to your printer. In the Selected port pane you can see if the port is occupied by some other application. If this is the case, you should wait for completion of the current job or should press Release port button, if you are sure that the present owner is not functioning properly.

4. Check if your application doesn't use special print options such as "-oraw"

If "-oraw" is specified as command line parameter for printing command, then remove it to print properly. For the Gimp application select "Print" item in the image context menu, then click "Setup Printer" button and edit command line of the printing command.

5. I can't print when I installed both Linux Print Package (LPP) and MFP driver on the same machine simultaneously

Since both Linux Printer Package and MFP driver make a symbolic link to "lpr" printing command, which is commonly used on Unix clones, it is not recommended to use both package on the same machine. If you still want to use both packages simultaneously, please install the LPP first. If you want to uninstall only one of them, please uninstall both packages and install that one you want to use again.

If you don't want to uninstall MFP driver and install it again, you may make the necessary symbolic link yourself. Please, log in as root user and invoke the following command:

ln -sf /usr/local/bin/samsung/slpr /usr/bin/lpr

 

6. I encounter error "Cannot open MFP port device file" when printing a document

Please, avoid changing print job parameters (via SLPR utility, for example) while a print job is in progress. Known versions of CUPS server break the print job whenever print options are changed and then try to restart the job from the beginning. Since Lnux MFP driver locks MFP port while printing, the abrupt termination of the driver keeps the port locked and therefore unavailable for subsequent print jobs. If this situation occured, please, try to release the MFP port.
