NAME
print - Print canvas and text widgets using native dialogs and APIs.
SYNOPSIS
tk print window
DESCRIPTION
The tk print command posts a dialog that allows users to print output from the canvas and text widgets.
The printing will be done using platform-native APIs and dialogs where available.
The canvas widget has long supported PostScript export and both PostScript and text files can be sent
directly to a printer on Unix-like systems using the “lp” and “lpr” Unix commands, and the tk print
command does not supersede that functionality; it builds on it. The tk print command is a fuller
implementation that uses native dialogs on macOS and Windows, and a Tk-based dialog that provides
parallel functionality on X11.
PLATFORM NOTES
macOS The Mac implementation uses native print dialogs and relies on the underlying Common Unix Printing
System (CUPS) to render text output from the text widget and PDF conversion of the canvas data to
the printer or to a PDF file.
Windows
The Windows implementation is based on the GDI (Graphics Device Interface) API. Because there are
slight differences in how GDI and Tk's canvas widget display graphics, printed output from the
canvas on Windows may not be identical to screen rendering.
X11 The X11 implementation uses a Tk GUI to configure print jobs for sending to a printer via the
“lpr” or “lp” commands. While these commands have a large number of parameters for configuring
print jobs, printers vary widely in how they support these parameters. As a result, only printer
selection and number of copies are configured as arguments to the print command; many aspects of
print rendering, such as grayscale or color for the canvas, are instead configured when PostScript
is generated.
