I’m using an old Mac Mini running regular OS X 10.4 “Tiger” to share an attached laser printer with the local network. For some reason, the two Windows laptops here (Windows Vista & Windows 7) can’t print PDFs with Adobe Reader. Printing from any other application works however.
I’m sick of debugging problems like this and instead shared a folder on the Mac Mini that is “watched” by a shell script that immediately prints every PDF that gets thrown in there, and deletes it afterwards. We share this folder with Dropbox, so this could also be used to print from about anywhere to your home printer.
The actual printing is done with an AppleScript that uses GUI scripting to send the keystrokes
⌘W to Preview.app after the PDF has been opened. While this isn’t very flexible (it always uses the default print options), it’s simple and probably covers 95% of the printing needs here.
Note that this doesn’t work well if someone is actually using the Mac where this is running on. You also need to “Enable access for assistive devices” in the Universal Access System Preference pane for the AppleScript to work (more details here).
I used the extension
.command for the shell script to allow it to be opened directly with the Finder, then dragged it to the Dock and enabled “Open at Login” from the contextual menu. Okay, cron would probably work too.
#!/bin/bash script_dir=`dirname "$0"` print_dir=/path/to/shared/print/folder cd $print_dir while [ 1 ] do # http://bit.ly/bmvIih find . -type f|grep -i .pdf$ |while read file; do echo Printing "$file" /usr/bin/open -a Preview.app "$file" /usr/bin/osascript $script_dir/print_pdf.applescript rm "$file" done sleep 10 done
Put it in the same folder as
The delays in the script are pretty arbitrary, your milage may vary.
tell application "Preview" activate tell application "System Events" tell process "Preview" keystroke "p" using command down delay 5 keystroke return delay 10 keystroke "w" using command down end tell end tell end tell
