| + | ==== Issues printing to the copy machine ==== | ||
| + | |||
| + | Most of the issues are due to incorrect code sent to the copy machine. | ||
| + | |||
| + | If you experience problems printing from KDE or command line, follow these instructions: | ||
| + | |||
| + | == Kde: == | ||
| + | For some reason KDE incorrectly writes the options for this printer. This is a KDE bug against Canon drivers. | ||
| + | |||
| + | - Edit the following file: <code>~/.cups/lpoptions</code> | ||
| + | - If there is a line regarding ''copy-t'' or ''copy-n'', remove that line. Sample correct file is as follows:<file> | ||
| + | Default printer | ||
| + | </file> | ||
| + | - If you want to specify custom options for the printer, set them in KDE, but then check the content of ''lpotions'' again, it should be something like:<file> | ||
| + | Dest copy-n ColourModel=Colour UserID=None UserPassword=None | ||
| + | Dest copy-t ColourModel=Colour UserID=None UserPassword=None | ||
| + | Default printer | ||
| + | </file> | ||
| + | |||
| + | == Commandline: == | ||
| + | |||
| + | It is good to test if printing works by command line. | ||
| + | |||
| + | To pass the codes to the print queue (should not be needed after you do the | ||
| + | KDE thing above, but in any case) issue the following: | ||
| + | |||
| + | ''lpr -o UserID=<code> -o UserPassword=<code> -Pcopy-t yourfile'' | ||
| + | |||
| + | It seems the driver for this printer is different than the previous one | ||
| + | and KDE always tries to fallback to some weird default. | ||
| + | |||
| + | ==== Firefox won't open: another instance is running or similar errors ==== | ||
| + | |||
| + | This happens in two cases: | ||
| + | |||
| + | == 1. You have firefox open in workstation A, and you try yo open it in workstation B == | ||
| + | |||
| + | **Solution**: It's advisable to close it in workstation A first. Each instance of firefox will write in the | ||
| + | same profile folder that might cause problems. To save your work you might want to use the [[https://addons.mozilla.org/en-US/firefox/addon/session-manager/|session-manager extension]] | ||
| + | |||
| + | == 2. Your machine shut down abruptly or lost connection with the fileserver before firefox released the profile lock == | ||
| + | |||
| + | **Solution**: remove the profile lock using this simple one-liner. **OBS**: make sure you **DO NOT** have firefox already running on some other machine or you will cause severe damage to your firefox setup!! | ||
| + | |||
| + | <code bash>find ~/.mozilla/firefox/ -iname '.parentlock' -exec rm {} \;</code> | ||
| + | |||
| + | And try to restart firefox again. | ||
