PRINT BECAME VERY LIGHT,HOW TO IMPROVE?

page setup,the most dpi it can handle or get a photo printer

Use Epson Photo Paper, and set your printer to "best" quality.
I could help you better if you would:
1. give model of printer
2. tell me what paper you're using
3. what the problem is with your photos.

Whats the question?? if poor quality printing, it could be dirty ink cartridges, dirt on the print head, poor quality paper ??? try looking at the printer settings, sometimes they may be set to economy rather than top quality printing.

Once Check your Cartage and try to Reinstall your Drivers in the system so that your problem get Solved

you can change the setting in the printer prefaces or do what i did keep an empty color cartage in the color slot and a good black cartage in its slot.

you need to replace the printhead...

get your printer service and get new INK jets mean Cartage for your printer thank you it will get no vertical lines then .. it is caused when cartages are leaking..

Try this:

The HP all-in-one product will print black copies using both the color and black cartridges to create composite black in Normal and Best modes. This is necessary to create the correct grayscale shades.

1. The color cartridge may be out of one color of ink. Perform the steps in the 'Colors are not correct' section above to verify that the ink cartridges are not low on ink.
2. Verify that the correct paper type is selected in the Paper Type setting.
3. Some photo paper has different chemical characteristics than Hewlett-Packard paper. The HP all-in-one is designed for use with HP Premium and Premium Plus Photo Paper. The photo paper, paper-type setting should be used with HP Photo Paper. For other paper brands, it may be necessary to use the plain paper or premium Inkjet paper, paper-type settings.

OR: The ink cartage you have may be defective if is a refilled or recharged cartage.

Set the properties to print on HP paper. This usually solves the problems

Try pushing it gently using some pressure. I had the same problem and it got solved using a little push.
