Printing Via LPR

If you have a Python app, or almost any kind of app, the accepted manner for printing is to use some kind of subprocess to invoke some command-line utility to submit the print job. Of course this requires that the underlying subsystems are aware of printers [and thus run a printer subsystem]. It also assumes the name of the command-line utility, the permissions are adequate to execute it, and all manner of other things. To put it simply: this is terrible! Why does my web server, workflow server, etc... need to run a print service?
