Using commands in a print job In addition to control panel settings, TIFF protocol can be selected by the PJL command: @PJL ENTER LANGUAGE = TIFF The following is a sample print job for a TIFF file: %-12345X@PJL JOB NAME="Sample.tif" %-12345X@PJL SET CLIP=OFF %-12345X@PJL ENTER LANGUAGE=TIFF < tif file goes here > %-12345X@PJL @PJL EOJ NAME="Sample.tif" %-12345X General rules The following are some general rules to describe how the D640 printer processes TIFF data. l Each TIFF file is a self-contained unit, made up of one or more sub-files. Each sub-file describes a single rectangular image. The image may be a complete page, or it may be a part of a page. During TIFF emulation, the printer cannot switch into any other protocol, except at the boundaries of individual TIFF files. l If a TIFF image contains multiple sub-files, the images contained in the sub-files are placed on separate pages in the order the sub-files appear in the TIFF data stream. l If TIFF is the selected protocol: • Images are placed with respect to the physical page, with zero margins. • If a sub-file doesn't have positioning information, the image is placed at the edge of the page. • If a sub-file has positioning information, the commands are interpreted as absolute displacements from the edge of the physical page.

General rules
The following are some general rules to describe how the D640
printer processes TIFF data.
Each TIFF file is a self-contained unit, made up of one or more
sub-files. Each sub-file describes a single rectangular image. The
image may be a complete page, or it may be a part of a page.
During TIFF emulation, the printer cannot switch into any other
protocol, except at the boundaries of individual TIFF files.
If a TIFF image contains multiple sub-files, the images contained
in the sub-files are placed on separate pages in the order the
sub-files appear in the TIFF data stream.
If TIFF is the selected protocol:
•
Images are placed with respect to the physical page, with zero
margins.
•
If a sub-file doesn’t have positioning information, the image is
placed at the edge of the page.
•
If a sub-file has positioning information, the commands are
interpreted as absolute displacements from the edge of the
physical page.
