D.2 Printable Area Compatibility
The printable area on the DEClaser 1100 is approximately the same as the
printable area on the LN03 printer. There is an approximate 6 mm (¼ in.)
nonprintable area around the page.
This difference does not affect any application using the predefined Page
Format Selections (PFS), or applications that do not print within 6 mm
(¼ in.) of the paper edge. When the LN03 printer encounters a character
that exceeds the printable area, it sometimes tries to shift the character
so that it falls within the printable area. The DEClaser 1100 printer does
not image any characters exceeding the printable area. This results in lost
characters.
D.3 Protocol Compatibility
The following list contains protocol compatibility issues between the LN03
printer and the DEClaser 1100 printer.
• The LN03 rounds a relative motion of 1 decipoint down to a relative
motion of 0, causing cumulative errors; the DEClaser 1100 keeps its
position accurately. This produces a side effect when a relative motion
of 0 is interpreted as a relative motion of 1 by both devices when using
decipoints. This leads to 0 motion on the LN03, and a 1 decipoint
motion on the DEClaser 1100.
• When trying to image past the bottom margin, the LN03 printer does
not always wrap. Wrapping depends on the glyph shape and the line
spacing. For example ‘‘j’’ may print but ‘‘a’’ may not. The DEClaser 1100
printer always wraps if the character box crosses the bottom margin,
even though the character may not have a descender. This ensures that
all characters either print, or all characters wrap to the next page.
• You should use the level 3 device identification for the DEClaser 1100
printer when possible. This allows the software to be compatible with
any future devices.
Some applications, such as DECmate, require you to set the printer
up to respond as an LN03 printer. When the device identification
is set to LN03, it responds as a base model LN03, not an LN03
PLUS, even though it may have sufficient memory for a full bitmap.
See Section 4.5.5.1 for additional information about the device
identification.
• The DEClaser 1100 does not support Tektronix mode; the LN03 PLUS
does.
