A common experience is to attempt to print a PostScript file which is too big to fit entirely within a printer's buffer. In this case, we recommend attempting to print the file with the unix command lpr -s filename. We remark in any case that piping data directly to a printer is somewhat riskier than creating a PostScript file and then sending that file to the printer, chiefly because if the pipe fails for any reason, then the image may be lost.
