Hi Kirk,
You can fix this by copying the following into the SmalltalkEditor class.

sendContentsToPrinter
| textToPrint printer parentWindow |
textToPrint := paragraph text.
textToPrint size = 0 ifTrue: [^self inform: 'nothing to print.'].
printer := TextPrinter defaultTextPrinter.
parentWindow := self model dependents
detect: [:dep | dep isSystemWindow]
ifNone: [nil].
parentWindow isNil
ifTrue: [printer documentTitle: 'Untitled']
ifFalse: [printer documentTitle: parentWindow label].
printer printText: textToPrint

this will send the contents of an editor pane to the connected (default)
printer.  If you need to change the printer, you can go to the outside top
left icon (mouse), choose VM Preferences->System Preferences->Printer
Configuration.

The above message also shows how to programmatically interface with the
printer.
