Limit a printer to a single copy of a document.
Eric Shepard sent in this great way to limit students (or co-workers!) from printing more than a single copy of a document.
I performed this edit on several of the chooser extensions for various printers, and it works perfectly. (Your mileage may vary.)
The file you want edit is called a Chooser extension. They can be found in the Extensions folder and will most often have the same name that's listed in the Chooser. Epson drivers behave differently and an example for them is shown at bottom.
 In this example, we'll modify an HP DeskWriter 310 driver.
Make a copy of the HP Chooser Extension and open it with ResEdit. Find the DITL resource and open it with a double-click.
 Find ID #-8191 and open it with a double-click.
(In the 6 different drivers on which I tried this edit, it appears that ID#-8191 always contains the Print dialog box.)
Find the section of the window that handles the number of copies. Double-click on the default number (1) to open the Item Options box.
Using the Popup menu, change the item from Edit Text to Static Text.
Close the windows, saving your work, and quit ResEdit. Replace the original driver with the modified one and restart the computer. (Keep the original close by for times when you may want to print multiple copies!)
The driver for my Epson 740 was a little different.
Since the Epson Chooser Extension didn't contain a DITL with ID# -8191, I began hunting and found it in a file called "Stylus COLOR 740 Library".
It was in Extensions-->Epson Folder-->Option Folder5 folder.
Once I found the corret DITL with ID# -8191, changing the text from Edit to Static worked the same as in the other drivers.
If you're in an educational enviroment, this small edit can help save you a ton of money on printer supplies. A student will be less likely to print out 200 party invitations if he has to do them one at a time! |
