Output Protocol
This control specifies the protocol that the product uses for print jobs. The following options are
available:
■ ASCII (default)
■ TBCP
■ Binary
When you click ASCII, data is sent in ASCII format (7-bit), which might take longer to print but can be
sent through any I/O channel, such as a serial, parallel, or network port.
When you click TBCP (Tagged Binary Communications Protocol), all data except special control
characters is sent in binary (8-bit) format. The binary formats can be sent over parallel or serial
communications ports and are faster than sending data in ASCII format.
When you click Binary, all data except special control characters is sent in binary (8-bit) format. The
binary formats can be sent over parallel or serial communications ports and are faster than sending
data in ASCII format.
Send Ctrl-D Before Each Job
This control specifies whether the product will be reset at the beginning of every postscript
document. The default setting is No. Ctrl-D resets the product to its default setting to ensure that
previous print jobs do not affect the current print job. Ctrl-D might cause a print job to fail if the
product is connected through a network. If your document fails to print when sent to a product
connected through parallel or serial ports, change No to Yes.
Send Ctrl-D After Each Job
This control specifies whether the product will be reset at the end of every postscript document. The
default setting is Yes. Ctrl-D resets the product to its default setting to ensure that future print jobs
are not affected by the current print job. Ctrl-D might cause a print job to fail if the product is
connected through a network. If your document fails to print when sent to a network printer, change
Yes to No.
Convert Gray Text to PostScript Gray
This control specifies whether to convert the true gray (RGB value) in text to the gray that the
postscript driver provides. It is set to No by default.
Convert Gray Graphics to PostScript Gray
This control specifies whether to convert the true gray (RGB value) in graphics to the gray that the
postscript driver provides. It is set to No by default.
Add Euro Currency Symbol to PostScript Fonts
This control specifies whether to augment the device fonts with the Euro currency character. It is set
to Yes by default.
Job Timeout
This control specifies how long the document can take to get from the computer to the product before
the product stops trying to print the document. If you specify 0 seconds, the product continues trying
