[fpc-pascal] Command line or CGI Printing

[Leonardo M. Ramé]

Nice!, and is it possible to send the bitmap data to lpr through a pipe?.

Something like "cat myfile.bmp|lpr". This doesn't work, it just prints garbage, maybe "cat" is handling the file as text.

I'm asking this because I don't want to create the file, then print it, then delete it, much better if I just create a TMemoryStream and send it to lpr.
