Free ink software for linux

Ink is a command line tool which displays the ink level of your printer. Ink project makes use of libinklevel.

Libinklevel is a library for checking the ink level of your printer on a system which runs Linux.
libinklevel supports printers attached via parallel port or usb.
Enhancements:
- Support for the following printers has been added: Canon i865, Canon iP3300, and Canon MP160.

The Digital Invisible Ink Toolkit is a Java steganography tool that can hide any sort of file inside a digital image (regarding that the message will fit, and the image is 24 bit colour). Digital Invisible Ink Toolkit will work on Linux and Max OS, even on Windows because it is written in Java and thus platform independent.

There are four highly customisable algorithms in the tool, as well as an open-source implementation of RS Analysis (an extremely good steganalysis method). The tool has the additional advantage of being able to simulate hiding - so you can get an accurate map of where the information is hidden.

The compiled version can be run by simply double clicking the .jar file, or by running at a command line with the following options (you will need to run at the command line if you are using big pictures, such as those greater than 500x500 pixels or it will run out of memory):

java -jar -Xmx512m diit_1-1.jar

Where -Xmx512m tells the virtual machine to use 512MB of physical RAM (at most) - please change to suit your own machine specifications.

Printbill is a sophistocated Unix print billing and/or accounting system with associated administration utilities. It primarily supports LPRng but now has limited CUPS support as well.
A simple print filter and accompanying daemon perform pre-printing billing, post-printing billing, print-accounting and print job quote generation. In addition, various utilities for administrators and users are provided - including programs to check your print quota and usage patterns, a web interface for both users and administrators and a command-line quote generator.
Charge rates may be specified on per-page, per-percent-coverage or both, and any number of printers/print queues can be provided (with different charge rates and printer parameters). Monochrome and CMYK colour printers are supported (with separate charge rates for both colour and black ink).
For all filters, processing can happen out-of-order, and you may prioritise jobs on the basis of size (jobs larger than a threshold can get lower priority or higher priority as desired) and jobs are billed in parallel / overlapping - jobs which finish billing first get printed first.
This is not necessarily the same as the order of arrival. Detailed stats are collected on a per-printer basis for job size, CPU time for each job, page count and ink/toner coverage, so you can analyse the usage patterns for your printers and predict when a cartridge will need to be replaced. It supports an optional user-supplied anything-to-postscript filter, so you can get properly billed for plain text, DVI files, image files, and so forth as well as PostScript.
Databases and configuration files may be stored on a centralised web server. This allows read-only access so that Unix (and conceivably Windows) clients could easily check quota, calculate quotes etc. remotely.
For fun, an additional filter is provided which allows users to deduct fixed amounts from their accounts (we use it to let students buy drinks and food from an unsecured laboratory fridge).
Enhancements:
- Finished support for per-user per-printer stats, tested that it works.

Print Plug-In provides a basic printing capability for The GIMP.
The current release supports PostScript, PCL (HP LaserJet and DeskJet), and ESC/P2 (EPSON Stylus Color) printers. The PostScript printer drivers handle PPD (PostScript Printer Description) files if you have them.
Using the Print Plug-In:
The Printer option provides selections for many common printers. Currently the print plug-in supports the following printers:
- PostScript printers
- HP DeskJet 500, 500C, 520, 540C, 600C, 660C, 68xC, 69xC, 850C, 855C, 855Cse, 855Cxi, 870Cse, 870Cxi, 1100C, 1120C, 1200C, and 1600C printers
- HP LaserJet II, III, IIIp, IIIsi, 4, 4L, 4P, 4V, 4Si, 5, 5FS, 5L, 5P, 5SE, 5Si, 6L, 6P printers
- EPSON Stylus Color, Color Pro, Color Pro XL, Color 400, Color 500, Color 600, Color 800, Color 1500, Color 1520, and Color 3000.
The Output Type option controls whether the printed output is in color or B&W (grayscale). This option is silently forced to B&W for grayscale images and B&W-only printers.
The Media Size option controls the size of the output. By default images are printed to fit the page and are automatically rotated to fill the largest area possible.
The Media Type option tells the printer what type of media is being used (Plain, Coated, etc). Not all printers support the media type option.
The Media Source option tells the printer which paper tray to print from. Not all printers support the media source option.
The Resolution option controls the resolution of the output. Not all printers support the resolution option.
The Orientation option controls whether the output is automatically rotated for maximum page coverage (Auto) or set to a specific orientation (Portrait or Landscape).
The Scaling option controls how large the printed image is. The default is to scale to a percentage of the printable area of the page. You can also specify an image resolution in pixels-per-inch (PPI) by clicking on the PPI radio button. The image is centered by default, however you can adjust the position of the image on the page by dragging the preview image.
The Brightness option controls the overall printed image brightness. A brightness of 100 is usually good for most B&W and PostScript printers, while most inkjet printers need a brightness between 100 and 120 for acceptable results.
Printing to a File
If you want to print to a file, select File from the Printer list. A file chooser dialog is displayed when you press the Print button. Warning, when you print to a file any existing file will be silently overwritten by this release of the plug-in!
Layered Images
Like most plug-ins, the print plug-in only reads the image from the active layer. If you want to print a composite of all visible layers you need to merge the layers (CTRL-M) and then print.
Supported Printers/Features
Most of the printer drivers in the print plug-in use the highest supported resolution for a printer, with the following exceptions:
- EPSON Stylus Color 600, 800, 1520, and 3000 - Currently the driver only supports 720 DPI printing in "compatibility" mode. This makes the drivers extremely slow compared to the Windows and Mac drivers. Unfortunately, I cannot provide optimized drivers (nor drivers for 1440x720) because of our NDA with EPSON.
- EPSON Stylus Photo, Photo Ex, Photo 700 - Currently the driver only supports 720 DPI printing in "compatibility" mode. This makes the drivers extremely slow compared to the Windows and Mac drivers, and you dont get the use of the light cyan and magenta inks (again, because of NDA restrictions.)

Synfig application is a powerful, industrial-strength vector-based 2D animation software package, designed from the ground-up for producing feature-film quality animation with fewer people and resources.

While there are many other programs currently on the market to aid with the efficient production of 2D animation, we are currently unaware of any other software that can do what our software can.

2D Animation has traditionally been very expensive because every frame must be drawn by hand. Even with todays digital inking and painting software, the process still relies on individuals hand-drawing each frame. This laborious task is called "tweening".

Our animation technology eliminates the task of manual tweening, producing smooth, fluid motion without the animator having to draw out each frame individually.
This allows you to produce 2D animation with fewer people while producing a product of a higher quality.

Please keep in mind that this release of Synfig Studio is considered a developer preview. IE: It is targeted at developers, not end users. That being said, feel free to play around with it -- just be sure to give it another chance later on down the road if you find yourself a bit frustrated.

GNUstep examples is a collection of programs that are meant to show programmers how to use GNUstep.
GNUstep examples includes a calculator, a currency converter, finger, fractal, puzzle, hostaddress, and ink (a simple editor).

Installation:
First make sure that your server is correctly configured to accept file uploads. With sites that use PHP you can make use of the included test.html and upload.php files to test your server configuration.
Depending on the version you have downloaded move dnd.jar, dndlite.jar or dndplus.jar onto your web space. Also move the included php files onto the same location as the jar file. Next open applet.php in your favourite text editor and change the url parameter to match your server-side upload handler. Thats it!
The upload.php is a sample PHP script provided to get you started on drag and drop file upload. You may need to modify upload.php to suite the needs of your website or web application.
If you prefer to use perl as your server side handler please copy upload.cgi to your /cgi-bin/ directory and change permissions to 755. Perl upload handling can be tested with test-perl.html
Each licence of Rad Upload Lite, Rad Upload and Rad Upload Plus allows you to install the applet on exactly one website.
Enhancements:
- A minor bug in client side filtering (by file type) and an incompatibility with tnftpd on Mac OS X were fixed.
