HELP Emergency printing many barcode in a page

It's hard to give advice without knowing your actual level of experience. You say you're a newbie, however, so I'll assume that there's more you don't know (but need to) than what you do know.

I would start by researching the simple mechanics of printing from a .Net app. Forget about bar codes; forget about a grid of stickable tags; just get ink on paper in a way that you understand what's going on.

Once you've understood managing a print dialog, setting its variables, getting values from it, deciding not to print if the user clicks Cancel, etc., and then (if the user clicks OK) printing your sample output (probably, a few lines of text in different font sizes), then you can move on to more sophisticated actions - such as iterating across a row of stickies, and down a page of stickies, and using a bar code font for that part of each sticker.

If you're so new to .Net work that you're not sure how/where to start researching what you need to know, google MSDN library; when you get there, search for print, or print dialog, print preview, or other possibly relevant terms.

Note that it's unlikely that anybody on Code Project will give you detailed step-by-step instructions for this (or questions like it). A little guidance is one thing, solving your problems for you is another thing altogether.

You should also note that your urgency is your problem and nobody here is likely to respond to "I'm in a hurry" remarks. If you have an imminent deadline that you're at risk of missing, you should communicate to the other person/people that you may miss the deadline and agree a new delivery date.
