As a general approach, writing output directly to a printer is to be
avoided. In many environments, printers are shared devices which are
accessed indirectly through print queuing software or network services.
The more general approach is to package the print output (presumably
as Postscript) and hand it off to a print server, possibly external
to Squeak. On a Unix box, the print server might be a program called
"/usr/bin/lpr". On Windows or Mac, in might be some other mechanism.
In the special case of a single user environment with a physically
attached printer and no printer handling software, it might be some
code in Squeak that calls ioFormPrint() to drive the printer device
