Printing a photo but not getting it upto your expectation.....?? No worries just fiddle a little bit
with the printing options and keep in mind some important points that I am going to tell will help:

1) RESOLUTION OF THE IMAGE TO BE PRINTED... Always keep in mind while printing a digital
printout that the resolution should be best fitted i.e. of the original photo.... if you stretch A photo too 
much or squeeze you might not get the desired result. It depends upon the DPI i.e
dots per inch that appear on the paper in the snap that you print. To get a quality print you must
make sure to select proper dpi for an image in printing. Eg. for printing a snap of 300 dpi you must choose
the image resolution as 600 dpi, but in case of professionally required image quality you can select upto 24oo dpi.

2) PRINTING PAPER ... Make sure that the paper you are using is suitable for the ink and the printer that
you are using. Certain printers specially design Photo Paper suitable for the ink used in them for eg. HP printers
do have Hp photo papers to give a good quality of image.

3) SETTINGS IN THE PRINTER... You can adjust the image quality that you want by clicking on the
Properties Option in the printer dialog box that opens when you give a print command. for eg. you can select
Economy mode for saving the ink (but this will not give a good quality image as colors to will be low),
or you can use the Bes option, as suitable for you...

So next time you Print a photo or snap of yourself make sure to remember these points and have fun.....

Good Luck!!

HP A636 will not print yellow; tricolor cartridge is new

  • Align the print cartridge.
The printer automatically aligns the print cartridge after a new one is installed. You can also align the print cartridge at other times to ensure optimal print quality. Indications that you need to align the print cartridge manually include borderless prints with white space
along an edge, colors not printing satisfactorily, or poor print quality.

To align the print cartridge from the printer
  1. Load a sheet of HP Advanced Photo Paper in the input tray.
  2. Touch the Setup icon to display the Setup menu. For more information, see "Setup Menu" on page 16.
  3. Touch Cartridge.
  4. Touch Align Cartridge and follow the prompts.

Clean the print cartridge automatically.
If the printed pages are missing lines or dots or contain ink streaks, the print cartridge might be low on ink or need to be cleaned.
CAUTION: Clean the print cartridge only when necessary.
Unnecessary cleaning wastes ink and shortens the life of the cartridge.

  • Clean the cartridge.
Follow these steps to clean the cartridge automatically:
To clean the print cartridge from the printer,
  1. Touch the Setup icon to display the Setup menu. For more information, see "Setup Menu" on page 16.
  2. Touch Cartridge.
  3. Touch Clean Cartridge and follow the prompts.
If the documents are still missing lines or dots after cleaning, replace the print cartridge.

Printing quality is very poor

The print quality of dat matrix printers depends upon the printer ribbon. If the ribbon is old or worn out then the print will be very light. In this case replace the ribbon.
Dot matrix printers are very old technology and I suggest you get a Inkjet printer or a laser printer.
Dot matrix printers cannot match the print quality of Inkjet and laser printers.

Poor print quality

The "ghost" image is "burned" onto the drum.

A laser printer is supposed to charge specific "dots" on the drum, and the toner-ink is supposed to stick only to those "dots", the paper is pressed against the drum, and then the "fuser" uses heat to "melt" the toner-ink onto the paper, to produce the printed page.

You need to replace the drum.

Print clarity

Check the print result by using Ink Management -> Testpage. After printing the test page, you'll get questions about the print quality, answer them and perform the cleaning after the questions. Repeat this process up to five times, which should solve the problem.

Greenish tint to black type

This is a dot matrix printer. The way they work is there is a print head that has a heap of little needles with flat tops on them, and they push out at high speed against the ink ribbon, and the ink ribbon is pushed against the paper to make a dot. Then the pin is retracted, spring loaded.
Pretty amazing that it can work that fast, eh!
So the only thing that can influence the ink colour on your paper is the ribbon.
Are you using original Lexmark ribbons? If so, my recommendation would be to take a sample print to where you got the printer from and get them to demonstrate the print quality of one of these printers, then compare it with yours.
Dot Matrix printers will not produce print as black or as high a quality as a laser printer, for example.
Perhaps the ink ribbons you are using have a less than top quality ink in them, and there is a bit of "bleeding" going on - it can only be the ribbon.
Another thing you can experiment with to get the best print quality is the print head gap - there will (should) be an adjustment, and getting that right will make a difference to print quality.
Hope this helps you.

the messages you get for cartridges other than the original are not trustful. You will get the right reading for original(from Brother) cartridges. Some ink is poor for printing photo quality.

not any refillable ink is right for printing photos, sometimes too dark, sometimes you don't get the right mix of colors.
