One of the most common enemies that disrupts printing in the library are massive .PDFs. Students will often send .PDFs that exceed 1GB.
Here is a method to greatly reduce the size of a PDF:
1. Launch Preview. From the Open menu, select the file you wish to reduce.
2. Export the file. From the File menu, select Export.
3. Set export options. Click the Quartz Filter menu, and select “Reduce File Size.”
4. Save. Select your desired location, then click Save. Your file will be saved in a much reduced size.
Let me know if you have any questions.
