D.2 Printable Area Compatibility
The printable area on the DEClaser 2200 plus printer is approximately the
same as the printable area on the LN03 printer. There is an approximate
¼" non-printable area around the page.
This difference does not affect applications that do not print within ¼" of the
paper edge. When the LN03 printer encounters a character that exceeds
the printable area, it attempts (in some instances) to shift the character
so that it falls within the printable area. The DEClaser 2200 plus printer
does not image any characters that exceed 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 2200 plus printer.
• The LN03 rounds a relative motion of 1 decipoint down to a relative
motion of 0, causing cumulative errors; the DEClaser 2200 plus printer
keeps its position accurately. If the printers receive a relative motion
of 0 decipoints, they interpret it as a 1. This leads to a 0 motion on the
LN03 and a 1 motion on the DEClaser 2200 plus printer.
• When trying to image past the bottom margin, the LN03 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
2200 plus 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 2200
plus 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 2200 plus printer does not support Tektronix mode; the
LN03 PLUS does.
• The DEClaser 2200 plus printer does not contain the Modern Gothic
font resident in the LN03 PLUS.
