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.

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
to print indefinitely. The default setting is 0 seconds. You can use the spin box to change this value
to a maximum of 32,767 seconds.
Wait Timeout
This control specifies how long the product waits to get more postscript information from the
computer. After the specified time passes, the product stops trying to print the document and prints
an error message. If you are trying to print a very complicated document, you might want to increase
this value. If you specify 0 seconds, the product waits indefinitely. The default setting is 300
seconds. You can use the spin box to change this value to a maximum of 32,767 seconds.
