The maximum print position (MPP) from PCIA byte X'0018'
specifies the maximum print position for each line of print. If
MPP is zero, the print line width is determined by the value set at
the printer control panel.
specifies the maximum print position for each line of print. If
MPP is zero, the print line width is determined by the value set at
the printer control panel.
If an entire print line does not contain any printable characters
(all are nulls, attributes, or in a nonprint field), it may not be
printed depending on how the XCTO‘s Null Suppression option
is set. In order to print a blank line, at least one character in the
line must be a space character within a print field, or the Null
Suppression option must be disabled.

Invalid control codes are treated as 'nulls'.
In addition to the printer control codes and graphic codes, the
data may contain screen-field attribute characters because the
printer can be used as local copy printer (copy screen image to
printer). A field starts with a field attribute (FA) character and
ends with the next FA character. Fields that cannot be printed
(e.g., input fields) are treated as blank fields and are called “non-
print fields.” The FA is normally the first character in a print order
and has the following definition, as shown in table E-3.

If the first character in a print order is not an attribute character,
the attribute of the first field is determined as follows:
the attribute of the first field is determined as follows:
• The print data is searched backwards for a field attribute from
MSA + ML-1 to MSA ignoring EM control codes. The first FA
found is then treated as if it had occurred at the MSA.
