Hi there, I've read several of the replies here and I noticed a flaw in your reasoning. In Windows, printers are generally set up to print pages, not single lines. In general, this means the printer works with documents and it will print the page(s) after the connection to the printer is closed again.
In your case, this just means you have to collect x lines of text first, until you have enough to fill a page. Then you can send those lines to the printer to have them printed. Remember, in Windows, the printer will not start printing before you tell it that the page or document is finished. Depending on your printer settings, your printer will print directly after you go to a new page or just when you close the printer document. In the latter case, it could take a long while before it's done. In general, it would be more logical to print these data lines to just a simple text file instead of to a printer. With a text file, you could simply use AppendFile to append text to the end of it. If you need a printed copy, then print the text file. A complex solution which probably doesn't work with any USB printer is by just contacting the printer directly through the LTP-port. This is pretty complicated stuff, though. And not advisable since it makes your application very printer-dependant. (Because you need to send commands to the printer that it will understand, and you need to be able to translate any error message that you receive from the printer. Again, printers are page-oriented, not line-oriented. You cannot print less than a single page. (Except for not printing anything, of course.) With kind regards, X Katja Bergman. --- In [email protected], soonhuat ong <[EMAIL PROTECTED]> wrote: > > I want a free component that can help me to print the data line by line as the following example: > > var myprintstring : String; > > for i := 1 to 5 do > begin > myprintstring := 'This is Line ' + IntToStr(i); > // Print data here > end; > > So the output will looks something like this: > > > > Output > ------- > > This is Line 1 > This is Line 2 > This is Line 3 > This is Line 4 > This is Line 5 > > > Anyone can help me out ? > > > > > > > > --------------------------------- > Start your day with Yahoo! - make it your home page > > [Non-text portions of this message have been removed] ------------------------ Yahoo!
