a) The Printer Package Specification for the CAMPS
project/4040 is written to fulfil the following
objectives:
1) To provide a detailed deinition of the Printer
Package function and Software architecture.
2) To provide user operational and development
personnel with details of the ongoing analysis.
3) To define in detail the interfaces with other
packages and to describe their acilities.
b) The Printer Package Specification defines the functions
and software architecture of the package to a level
sufficient for a programmer to start detailed design
with a minimum of design effort.
The Printer Package constitutes oneof the building
blocks of the TEP package.
All Printer Package internal data and interfaces
are defined within this document in detail. For
a detailed data description of data external to
the Printer package and interfaces to other packages
refe the Database Design Document (CPS/DBD/001)and
the relevant interface documents.

2.1 P̲A̲C̲K̲A̲G̲E̲ ̲D̲E̲S̲C̲R̲I̲P̲T̲I̲O̲N̲
The P̲r̲i̲nter P̲ackage (PRIP) contains the software to
support the print-functions required for
Supervisor Printers,
Shaed Printers,
Stand-alone Printers.
In connection with Supervisor printers PRIP has only
a slave function. The S̲upervisor P̲ri̲nter P̲ackage (SPIP)
supports the Supervisor Print functions and delegates
the items for print to the Printer Package.
t the Printer Package items will be queued in a priority
based FIFO-manner before being processed.
Items to be Processed can be:
a) Control Items:
Timeouts
DEMCO Commands
Log Acknowledges
FLASH Notifications
b) Print Items:
Mssages
Comments
Message status Notifications
MSO/MDCO instructions
Service Messages
Reports
Statistics
Log records
System Information Extracts
Tables.
The Printer Package converts and formats the data before
printout. I also takes care of page accounting and
document accounting.
The Printer Package interfaces with other parts of
the Terminal Package as well as other Packages of the
CAMPS system.
Fig. 2.1-1 shows the interface between the Printer
Package, and the other TEP Packages:
Supervisor Printer Package (SPRI)
VDU User Package (VUP)
Further fig. 2.1-1 shows th interfaces to the other
CAMPS packages:
System Status and Control (SSC)
CAMPS System Functions (CSF)
LOG Package (LOG)
Message Distribution Package (MDP)
I/O Control (IOC)
Storage and File Management (FMS)
Table Management Package(TMP)
The numbers on figure 2.1-1 refers to the following
table:
1. Supervisor print items
2. User print items
3. DEMCO Commands and Command Completion Codes.
4. Timer requests/events,
Queue handling, Access control
5. Final transactin Log information
6. Incoming/Outgoing Messages
7. Printout Data
8. MDCO MSO Print Items
9. Device profile data, Format execution data,
Printer Parameters.

The main functions implemented by PRIP are
1. Fomatting and printout
2. Document accounting
3. Preemption Control
2.2.1.1 F̲o̲r̲m̲a̲t̲t̲i̲n̲g̲ ̲a̲n̲d̲ ̲P̲r̲i̲n̲t̲o̲u̲t̲
Some of the items queued for print contains binary
data which will have to be converted into a displayable
form before being printed.
The iems do not contain all of the data to be printed.
The predefined part of it is contained in the Print
Format File (PFF) and must be merged with the variable
part to form the complete text.
The formatting also includes placing of the text so
that nice layout is obtained. Ref. also sec. 2.2.1.2
below.
When the text has been formatted, it will be output
to the printer.
2.2.1.2 D̲o̲c̲u̲m̲e̲n̲t̲ ̲A̲c̲c̲o̲u̲n̲t̲i̲n̲g̲
Document Accounting is to be carried out as stated
in the SRS sec. 3.2.3.7.2 for the follwing items:
- Messages
- Service Messages
- Comments
The layout of the document accounting is outlined in
figure 2.2.1-1 and figure 2.2.1-2.
Figure 2.2.1-1 explains the contents of the document
control number, while figure 2.2.1-2 shows the page
layout.
2.2.1.3 P̲r̲e̲e̲m̲p̲t̲i̲o̲n̲ ̲C̲o̲n̲t̲r̲o̲l̲
When items with Flash Precedence ae queued for print
they shall start being executed within a specified
time limit unless the printer process already executes
a Flash item.
If the item being executed is of precedence lower than
flash and it cannot be completed within the time limt,
it shall be preempted. Processing of the preempted
item shall be resumed right after the preemption causing
item has been finished.
The preemption time limit is set by the Supervisor.…86…1

PRIP performs the above functions on command from DEMCO.
a) Start:
Initializes and starts the prnting actions. Also
the Print Format Handler is initialized. Upon completion
a report will be sent to DEMCO.
b) Stop:
Immediately stops the printing actions. The items,
that is currently processed, will be returned to
its queue for later procesing.
Completion is reported to DEMCO.
c) Close Down:
Stops the printing actions after a specified time.
Is used to terminate the processing in an ordered
manner. Completion is reported to DEMCO.
d) Resume:
Is used to resume printing ations after printer
errors.
2.2.2.2 C̲h̲e̲c̲k̲p̲o̲i̲n̲t̲i̲n̲g̲ ̲a̲n̲d̲ ̲R̲e̲c̲o̲v̲e̲r̲y̲
Checkpointing is performed by calling the SAVE-function
(CSF) at appropriate points, that is when print out
of an item has been completed. The ueue element will
be dismantled.
On recovery some of the items queued for print may
have a flag set indicating suspected duplication. In
that case it shall be indicated on the document.
2.2.2.3 E̲r̲r̲o̲r̲ ̲D̲e̲t̲e̲c̲t̲i̲o̲n̲ ̲a̲n̲d̲ ̲E̲r̲r̲o̲r̲ ̲H̲a̲n̲d̲l̲i̲n̲g̲
PRIP is desined so that errors are detected at an early
stage.
All detected errors, i.e. System Call errors, Queue
errors, internal software errors, etc, are handled
by using the CSF procedures ANALYZE ̲ERROR and SEND
̲GARBLE.
2.2.2.4 I̲n̲t̲e̲g̲r̲i̲t̲y̲ ̲o̲f̲ ̲O̲p̲e̲r̲a̲t̲i̲o̲
The error detection and error handling functions described
in section 2.2.2.3 ensures that errors are detected
and handled properly.
Single and minor software errors do not decrease system
throughput. Only severe errors cause major recovery
orinvoke operator intervention.

The log record shall contain the following fields:
a) Device designator
b) Transaction serial number
c) Format identification
d) Log time
e) Item reference identification
f) Exit cause
g) Classification
