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 “SNA Character String (SCS) Support” 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 printer session.

  • SNA IMF supports platen widths of 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 PRINT softkey 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 “AS/400 5240 to Pass Thru 3270 Mappings” for a comparison of how these four characters are represented by HP and IBM devices.

  • Appendix C “Pass Thru Terminal and Printer Specifications” lists the HP printers that can be used with Pass Thru.
