If your files were created on a Macintosh and you are using Postscript Type 1 fonts, you will need to send both the printer fonts and the screen fonts; with Truetype fonts, there are no separate printer and screen font files to worry about. These files will most likely be found in the fonts folder located inside your Mac’s system folder. Simply highlight the fonts you need to collect, and drag them to the folder or disk onto which you are going to copy the fonts while holding down the option key. Please note that it is critical to hold down the option key in this process. Otherwise, you may move the fonts instead of copying them.
On the PC, the most common font format is Truetype (.ttf files). These files will most likely be found in the fonts folder located inside your PC’s Windows folder. If you are using Postscript Type 1 fonts, you will need to send both the printer fonts and the screen fonts (there will be 2 files with the same name, except for the file extension of .PFB and .PFM). Simply highlight the fonts you need to collect, click Edit/Copy in your Windows Explorer window, move to the folder or disk onto which you are going to copy the fonts, and select Edit/Paste in your Windows Explorer window.
