Several different things are polymorphically called print. How do I send text to a peripheral printer? I found the menu item "Send contents to printer" and it produced walkback which says "MessageNotUnderstood: SmalltalkEditor>sendContentsToPrinter". Printer setup similarly failed yet after the OS supplied the customary sound that the printer was hooked up.

This occurred in Squeak 4.5 under Windows 7. What would solve the problem best? Upgrading Squeak? Getting a different printer? Going back to Digitalk Smalltalk/V and a dot matrix ribbon printer where it did work years ago?

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.
