Printer driver hp photosmart 55201/27/2024 It also describes how the intermediate values move from 0 through to 255 – known as the tone response curve (or sometimes “gamma”).Įxamples of colour spaces are (Adobe RGB1998, sRGB IEC61966-2.1) This is the job of the document profile which describes the exact colour to be shown when Red=255 and what colour of white is meant when Red=255, Green = 255 and Blue =255. What colours do the numbers in the document represent? To ensure the output device is showing the correct colours then a colour management system needs to know two things.ġ. shop and look at the different coloured pictures – all from the same material. To see a demonstration of this, walk into your local T.V. The problem comes in that different devices can be sent those same numbers but will show different colours. In RGB mode, each pixel has a number representing Red, a number representing Green and a Number representing Blue. You should never substitute a monitor profile for a printer profile.ĭigital images are made up of numbers. Some folk use the equipment to produce their own printer profiles ( I do here) some use the profiles from the paper/printer manufacturer which are often quite accurate. That will be very different to the behaviour of a monitor. The printer profile has to describe the behaviour of your printer using a particular paper and ink set. A monitor profile should never be used as a printer profile. It is produced in a similar way but with different hardware (a spectrophotometer). The printer profile describes the printer. That is used to build a profile describing your actual screen. So the profiling software sends a set of known colours to the screen and reads what actual colour is produced. To produce an accurate profile requires a hardware device which reads colours off the screen. Whilst you can use a generic profile for the monitor - it can only be close to describing your monitor. The monitor profile and printer profile are two separate things. Your action may have got your colours closer but is not the correct way to colour manage. Please can I have walkthrough that works on how to get this printer working, thanks very much.After reading your post here's what I did:ġ) I downloaded hplip-3.14.10.run (but I didn't bother downloading the digital certificate).ģ) I dragged hplip-3.14.10.run into the Terminal window.ĥ) hplip-3.14.10.run then appeared ready to walk me through its installation (but I went no further since I don't have a printer).I've unmarked your answer as correct as it could mislead other people, and made sure D.Fosse's answer is highlighted as the correct answer.

I'm not sure I understand why ubuntu cant just allow me to click the file with my mouse and simply install it that way? Sh: 0: Can't open anyone please help as I'm totally stuck? I drag the downloaded driver file onto my desktop, but the terminal comands wont work for cd desktopīash: cd: desktop: No such file or sh hplip-3.14.10.run I tried this advice: /hplip-web/gethplip.html Maybe manually installing a driver would help?Ĭon somebody please explain how to run the downloaded file? I tried doing it with the menu and choosing my printer from the dropdown list, and it seemed to recognise it, but when I print a test page, absolutely nothing happens at all. Most things are working ok, but I can't get the printer to work. I had to put in Ubuntu on this comp0uter as windowsw died.
