I got a new computer with Windows 7 and downloaded a driver for my hp 3210xi printer. I am trying to print a 4x6 picture but I can't seem to access the photo tray even though I have indicated to use the photo tray and appropriate size paper - the printer only wants to use letter size paper.

There is no downloadable driver for this printer. You just need to update the Windows 7 list on your computer with the latest update. Here are the instructions from hp:

Hi- Have you tried downloading and installing the windows 7 drivers from hp? HP PSC 1315 Windows 7 drivers

Thanks

It seems that the issue is with the driver of your computer and it is not letting you print. You can therefore download new upgraded set of drivers from http://h10025.www1.hp.com/ewfrf/wc/product?product=90764&lc=en&cc=us&dlc=en&dlc=en&lang=en&cc=us
Once downloaded, try to run the downloaded program and uninstall your printer using it and restart your computer. Now run the downloaded software once again and install your printer. It will now work fine. Remember do not uninstall Printer's driver from Add/Remove Programs (Winodws XP) or Programs and Features (Windows Vista and Windows 7).
Enjoy printing once again.
Cheers!

You need drivers for win 7 only for the two printers you have .some of the mfg, have not got all the bugs out as yet. Im in the same boat .had to get a new model so i could print. Check windows web. site for driver 7up dates.hope this helps

When you select paper size, are you doing it in the "Printing Shortcuts" tab or the "Paper Options" pane of the "Paper/Quality" tab?

On the "Printing Shortcuts" tab, the options available in the Paper Size box vary according to your selection in the "What do you want to do?" box. If you select "General Everyday Printing" it will not show paper size options for photos, postcards etc. However, if you go to the "Paper/Quality" tab you should be able to select 4x6, 5x7, 8x10 etc.

if you trying to prints the picture from windows media player you need to press print and then by windows side its going to show how you want your pictures 4x6 or whatever when you do that try to set up the printer tray the same side of the paper you only move the tray with hands i hope this work for you
