Printing Binary Data (USB or LPR connection)
Users may experience problems printing files with binary data to the Elite 21 printer
using a USB or LPR-based connection due to the way that binary information is
processed via these protocols. LPR users should see the note on
configuring the printer's IP Data Format setting. GCC has also developed a printing
plug-in called a TBCP (Tagged Binary Communications Protocol) Filter which resolves
this problem, however users must be using MacOS 9.0 or higher with LaserWriter
driver version 8.7 or higher for this file to work.
Options for users of Mac OS 8.x (using LaserWriter 8.6.5 or below)
• Try disabling Binary printing, as follows:
• From the Desktop, go to File and Print Desktop.
• In the Print window, hold down the Option key on the keyboard and click on the
General pull-down menu.
• An item marked "Preferences" should appear at the bottom of the list. Pull down
to this item.
• A list of printing preferences will appear. Check the list item marked "Never
Send Binary Data." Do not make any other changes to the options. Click
"Save Changes" to accept.
This will keep the driver from generating binary data when sending jobs to the
printer. It will not, however, resolve issues with embedded binary data within print
jobs (binary EPS graphic files embedded in a document, for example). If problems
with binary files continue, you may need to pursue one of these other options:
• Switch from USB to a standard AppleTalk connection. The AppleTalk/EtherTalk
protocol does not have this issue with binary data.
• Make sure that all elements (graphics, etc.) are saved in ASCII format within the
applications that produced them.
• Upgrade from MacOS 8.x to MacOS 9.x and use the TBCP Filter as outlined on the
next page.
