Setting line density for RJE devices

You can select the line density for a remote printer by:

Specifying the FCBLOAD parameter on either the R(nnnnn).PR(m) initialization statement or the $T R(nnnnn).PR(m) operator command.
Turning on bit 4 of byte 4 in the PSERVIC field of the JES2 RJE bind image.

This causes JES2 to select the proper density (6 lines per inch or 8 lines per inch).

Certain older printers (for example, the 3777-1 and the 3776-1) cannot have their densities set with PSERVIC's bit 4 of byte 4 set on and require the standard JES2 bind image. If you receive message $HASP190 at your remote printer, you must manually advance the form in the printer to line 1 of the page before starting the printer. This will cause the PSERVIC byte to look like this:

    PSERVIC=X'011000009900C00000010040'
