Cci members doesnt help.........?

as per practice in IT industry, use the best possible monochrome printer unless specified for colour printer, 

so you have to use black and white laserjet, ( if you have some 600 dpi colorjet then it will alsol work)

Use laserjet printer. basically the print has to be clear & vigible

If you have completed your articleship, then attach articeship completion certificate., else nothing is required, because if your articleship is still not completed, then your prinicipal will be certifying regarding  the same.

Do not take back to back print, take it in a seperate sheet.

Please do not fold., use  A4 Size envelope to post the same.

Hope it is clear now.
