The passthru Interface

This interface is for use by devices that are not printers, or by printers that are not controlled via the standard RTE printer interfaces. All HP plotters that do not have text printing capability fall into this category. There is only one model file associated with the passthru interface; that

model file is also named passthru.

No processing of the data stream or meddling with the output is performed by this interface; the print output is sent as is to the device. This is similar to the effect of the raw option supported by many of the other interfaces. Transparency (or honesty) mode is always used in the device driver, if one exists for the device. See the RTEA Driver Reference Manual, part number 9207790011, for more information on the operation of the various RTE device drivers and on the transparency or honesty mode processing. No data or control requests other than those specified in the print data are sent to the device. No banner page is printed; no page ejects, control requests, or device resets are performed by the interface.

Printer interface options may be specified in the lp program runstring preceded by a -o. This interface supports the following options:

DDevice Handling:

kc

The files include EXEC control word headers. The files must have been created by

 

the ON command of the SP spooler with the KC option specified. These headers

 

specify the control word flags that were used in the redirected EXEC/XLUEX

 

writes and preserve information on control requests that were sent to the redi

 

rected device. This option has no effect on type 1 files.

DOther:

hold

Suspend operation before and after printing the request, while the printer LU is

 

locked to the lpout program. Both times, lpout prints a message on the system

 

console of the form:

 

prog: suspending per user request; enter ”GO,prog” to resume

 

where prog is the program name of the lpout copy that is suspending. The copy of

 

lpout handling the print operation remains in the •paused" state until an RTE

 

GO command is issued for that program name. In this manner, adjustments to the

 

printer, such as forms loading, may be performed before and after the request is

 

printed.
