XEROX LASER PRINTING SYSTEMS TAPE FORMATS MANUAL 13-1
13. 13NCR tapes
The Xerox printer accepts NCR Century B1 Operating System tapes
that meet the following criteria:
• ASCII character code
• ANSI standard label or unlabeled
• Four-byte carriage control, as described in this section
• Fixed block format or other supported generalized format
• B1 COM spool tapes or B1 Interim Print Files, as described
below.
The ANSI labels conform to the requirements of ANSI Standard
X3.27–1969 (see chapter 1). The block and record format may be
any of the types that can be described by a JDL.
The print record should not have any embedded control characters
such as those for blank compression. If embedded control characters
are contained in a print record, they cause no carriage control action
to occur and generally print as a blank.
Carriage control conventions
The carriage control is 4 bytes long. Processing parameters for NCR
carriage control, using the PCC definitions from the PDL system
command set, are as follows:
NCR
INITIAL TOF
DEFAULT IGN,SP1P
ADVTAPE NO
MASK X‘FF‘
ASSIGN See “Printer control block codes.”
