Restrictions on 3287 Printer Emulation
SNA IMF allows printers attached to an HP 3000 to emulate IBM 3287
printers, with the following restrictions:
* SNA IMF does not emulate extensions to the SCS data stream.
Appendix B lists the SCS control codes emulated by Pass Thru.
* You cannot emulate pressing the IBM 3287 HOLD PRINT, PA1, PA2,
CANCEL, and ENABLE PRINT keys in an LU.T3 printersession.
* SNA IMF supports platen widthsof 40, 64, 80, and 132 columns for
an LU.T3 printer. For an LU.T1 printer, SNA IMF uses the Set
Horizontal Format (SHF)SCS control code to define a platen width
less than or equal to 132 columns. The default is 132 columns.
* SNA IMF cannot emulate the extended character set of the IBM text
print feature. Therefore, it cannot emulate the Suppress Index
(SI)feature of an IBM 3287 printer.
* SNA IMF does not support the local copy(PRINT key) function of IBM
3278 display stations. Two printer options are available to take
the place of the local copy feature:
1. You can use the PRINTsoftkey to send a copy of the internal
screen image to a spooled printer file called LOGIMF. Use a LOGIMF
file equation to identify the device class you want to use. The
LOGIMF file equation defaults to device class LP. See chapter 2,
"Configuring Pass Thru," for information on the PRINT softkey.
2. The HP 2645 and later model terminals support printers slaved
directly to them. You can use your terminal softkeys to do local
printing; however, the Pass Thru PRINT softkey cannot be used to
send data to a slaved printer.
* SNA IMF represents four HP terminal characters (the left bracket,
right bracket, exclamation point, and caret) differently on an HP
printer than on an IBM printer. See table 5-4 for a comparison of
how these four characters are represented by HP and IBM devices.
(on IBM terminal)
* Appendix C lists the HP printers that can be used with Pass Thru.
