EPSON LQ-590 printing error

There is no downloadable driver from Epson's web site for 7 and even Vista.
You should try another generic dot-matrix printer driver.

which one please advice for latest driver

I'm not sure from your Question exactly what you mean, with "it prints almost access papers also". Are you saying more pages come out than you are actually printing? If yes, are those pages empty?

If yes, make sure you select the proper paper size in your printer driver before printing. If the size doesn't match the size you have in the printer, it'll typically throw out more pages than necessary.

Also, many dot matrix printers have dip switches where you can setup the printer, so check those settings (although usually the printer driver of windows overrides those settings).

If my assumption isn't correct, please give us some more details of your problem.

Add a new printer. At the producer's and model's window select "Generic" instead of Epson and select one of the 3 first models (they are all generic printers).

please give me standard size of paper to be choose for dot matrix printer also link for updated driver for same

You should know which kind of paper are you using.
There is no link to updated drivers. The generic drivers are (already) provided with Windows 7.

The size is probably printed somewhere on the paper's packaging.

thanks

You are welcome.
