waaay back in lesson 04 we looked at a script to automate printing (and lessons 05 and 06 explained how some of the script elements worked).
well, finally, it’s time to take printing automation to the next level. the original script prompts the user to select a print preset from a list. but that’s too much like hard work. what if the script could automatically decide which preset to use based on the document specs?
apologies to you lovely people in the States — we’re going to be using metric for this example because, well, it is the twenty first century after all and anything referred to as ‘imperial’ should be long dead.
the first part of the script captures a few bits of information from the document preferences. facing pages is boolean, so it returns true or false. page orientation returns landscape or portrait (square pages return portrait too). page height and width return real numbers in whatever measurement unit you’re using :
tell application "Adobe InDesign CS6"
tell active document
set mgPgFace to facing pages of document preferences as string
set mgPgOrnt to page orientation of document preferences as string
set mgPgHght to page height of document preferences
set mgPgWdth to page width of document preferences
end tell
end tell
display dialog (mgPgHght as string) & " : " & (mgPgWdth as string) & " : " & mgPgOrnt & " : " & mgPgFace
so, for a single A4 page the resulting dialog will look something like this :
now, if you’re a neat freak (and aren’t we all?) you may prefer your real numbers converted to integers. notice that you can’t coerce a real to an integer as it is captured — the conversion has to be done separately :
tell application "Adobe InDesign CS6"
tell active document
set mgPgFace to facing pages of document preferences as string
set mgPgOrnt to page orientation of document preferences as string
set mgPgHght to page height of document preferences
set mgPgWdth to page width of document preferences
set mgPgHght to mgPgHght as integer
set mgPgWdth to mgPgWdth as integer
end tell
end tell
display dialog (mgPgHght as string) & " : " & (mgPgWdth as string) & " : " & mgPgOrnt & " : " & mgPgFace
then you’ll have neat (not necessary, but neat) :
…and you can get rid of that display dialog line now — dialogs are a handy way to check your progress when developing a script.
ok, now, the complexity of the next bit is dependant on the complexity of your workflow. the workflow this script was developed for has only eight possible scenarios, roughly like so :
so, all we need to do is find out which of the scenarios our document falls into and select the corresponding print preset (which we’ll capture into the variable mgPrintPreset). let’s start with the two facing pages options (printed as spreads) :
if mgPgFace is "true" then --print document as spreads
if mgPgHght is greater than 277 or mgPgWdth is greater than 200 then --use A3 fit preset
set mgPrintPreset to "A3S fit"
else --use A3 100% preset
set mgPrintPreset to "A3S 100%"
end if
else --print document as single pages
--(scripting bits for single page options go here)
end if
this shows the basic approach to these kinds of problems — if/then/else. if something is true, then do this thing, else (otherwise) do this other thing. we just need to break the problem down into pairs of options.
and we can still use this method for eight different scenarios because if statements can also be nested — ifs within ifs. the full code for dealing with all eight possibilities looks like this :
if mgPgFace is "true" then --print document as spreads
if mgPgHght is greater than 277 or mgPgWdth is greater than 200 then --use A3 fit preset
set mgPrintPreset to "A3S fit"
else --use A3 100% preset
set mgPrintPreset to "A3S 100%"
end if
else --print document as single pages
if mgPgOrnt is "portrait" then --use one of the vertical presets
if mgPgHght is greater than 277 or mgPgWdth is greater than 200 then --use one of the A3 presets
if mgPgHght is greater than 400 or mgPgWdth is greater than 277 then --use A3 fit preset
set mgPrintPreset to "A3V fit"
else --use A3 100% preset
set mgPrintPreset to "A3V 100%"
end if
else --use A4 vertical preset
set mgPrintPreset to "A4V"
end if
else --use one of the horizontal presets
if mgPgHght is greater than 200 or mgPgWdth is greater than 277 then --use one of the A3 presets
if mgPgHght is greater than 277 or mgPgWdth is greater than 400 then --use A3 fit preset
set mgPrintPreset to "A3H fit"
else --use A3 100% preset
set mgPrintPreset to "A3H 100%"
end if
else --use A4 horizontal preset
set mgPrintPreset to "A4H"
end if
end if
end if
but it’s easier to understand in a screen grab of the code in script editor :
the bits in quotation marks are the names of the InDesign print presets, the green elements are the variables (remember you can name variables anything you like, just as long as it’s not a term reserved by applescript), and the other coloured bits are comments to help us keep track of what we’re doing. comments are preceded by two hyphens and are not actually part of the code — they’re little reminders that are especially helpful when revisiting the script sometime in the future.
the last line of code simply tells the document to print using the selected print preset :
print using (mgPrintPreset as string) without print dialog
cobble all those bits together and the complete script for this workflow looks something like this :
now, obviously you’re not going to be able to use this one straight out of the box — you’ll have to do a little work to update it to your page sizes and print presets and whatnot to suit your workflow.
but once you’ve set it up you can do all your printing with a double click — rather than cmnd-p, click, choose, click, click …
OR, even better, reassign the cmnd-p shortcut to run your script.
bonza.
applescript services can be created through automator — the automation program that comes standard on every mac since OS X 10.4 (you’ll find it in your applications folder).
