You can toggle various modes of operation for the imagePROGRAF PRO-300 from a Mac. Follow the steps below to specify these modes of operation.

1. Select Custom Settings from the pop-up menu in the Canon IJ Printer Utility.

    If the computer is unable to communicate with the printer, a message may be displayed because the computer cannot access the function information that was set on the printer. If this happens, click Cancel to display the most recent settings specified on your computer.

2. Adjust the following settings as desired:

   Detects compatible media in the multi-purpose tray

   Detects whether compatible media is loaded on the multi-purpose tray during printing using the multi-purpose tray, and displays a message if compatible media is not loaded.
   Check this check box to detect whether compatible media is loaded when printing.
   Uncheck this check box to print without detecting whether compatible media is loaded.

    If you leave this check box unchecked, the printer may print to the multi-purpose tray even if compatible media is not loaded on the multi-purpose tray. Therefore, you should check this check box under normal circumstances.

    If you load compatible media that has already been printed onto the multi-purpose tray, the printer may detect that no compatible media is loaded on the multi-purpose tray. In this case, uncheck this check box.

   Don't detect mismatch of paper settings when printing from computer

   When you print documents from your computer, the paper settings in the printer driver and the paper information registered on the printer do not match, this setting disables the message display and allows you to continue printing.
   To disable detection of paper setting mismatches, select this check box.

   Disable paper width detection when printing from computer

   Even if the paper width identified by the printer during printing from the computer differs from the paper width that was set for Paper Size in the print dialog box, this function disables the message display and allows you to continue printing.
   To disable detection of the paper width during printing, check this check box.

3. Click Apply and when the confirmation message appears, click OK.

   The printer will operate with the settings specified.
