Printing a line instead of "--------"

For a Windows CE project that we print slips, we have a new request which asks if it is possible to print a line insted of printing "-----------" all the way.

Is this possible without printing an image?

c# / .net 3.5

On your desktop run charmap.exe. Tick "Advanced view" and type "box" in the Search box. You'll get the Unicode codepoints that you can use to draw lines and boxes. Copy and paste them into your code. Whether they actually show up properly on your device depends on the font support. Odds are decent since they've been around since the first IBM PC. You'll have to try.

There are extendedascii values to do this (196) but it really depends on the printer.

Or as quppa comments use _ but it will not be adequate if you want to box in a title or so.

Wikipedia has an article on box-drawing characters.

Since ─ (U+2500) didn't work for you, it's unlikely ━ (U+2501) will work either, but it's perhaps worth a shot. There is also no guarantee that there won't be spaces between these characters, given that spaces appear between underscores.

The issue is not Windows CE supporting Unicode but finding a font that you can use that has the box-drawing characters. Given the likely size limitations (fonts with lots of characters are tens of megabytes big), this might be a challenge.
