You can't use pipes.
lpr relies on the file extension to determine the file type and invoke the
proper filter.
When using pipes, it assumes postscript AFAIK.
In each case creating the file doesn't hurt. LP will create a file anyway.

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.

without using the Printers unit. I can't use it because it

without X installed.

For more details: man lp
Print a double-sided legal document to a
printer called "foo":
lp -d foo -o media=legal
-o sides=two-sided-long-edge filename
Print an image across 4 pages:
lp -d bar -o
scaling=200 filename
Print a text file with 12 characters per
inch, 8 lines per inch, and a
1 inch left margin:
lp -d bar -o
cpi=12 -o lpi=8 -o page-left=72 filename
Or just print the file to the default
printer
lp "my long
file.txt"
