Xerox 6287 user manual Allow Xerox 36h transparency, Pseudo transparency

Page 3-22 6287 ALLY PLUS User’s Manual

If this option is set not to allow 35h transparency (00), then the trigger, the count byte and all of the otherwise transparent characters will be printed normally, as indicated by the active translate table (see Section 5 — Translate Tables). Refer to Section 7 — SCS Data Streams for more information on IBM 35h transparency.

Program this option by using one of these two sequences:

!ALLY!60=00; 35h transparency disabled

!ALLY!60=01; 35h transparency enabled (default)

61 — Allow Xerox 36h transparency

This form of transparency is identical to 35h transparency, except that the trigger character is 36h. Xerox applications typically use 36h instead of 35h to send data directly to the printer. If this option is enabled (01), the ALLY PLUS detects the trigger, picks up the count byte and starts “passing through” the remaining data.

If this option is set to 00 (the default), the trigger, the count byte and all of the otherwise transparent characters will be printed normally, as indicated by the active translate table (see Section 5 — Translate Tables). To program this option:

!ALLY!61=00; 36h transparency is disabled (default)

!ALLY!61=01; 36h transparency is enabled

62 — Pseudo transparency

The ALLY PLUS has its own form of transparency, called pseudo transparency mode (PTM). Unlike IBM 35h and Xerox 36h transparency, pseudo transparency can be used in both SCS and DSC data streams.

This type of transparency has two forms: one trigger (trigger+count byte) and two trigger. It also may be disabled altogether. The programming sequences for this option are:

!ALLY!62=00; pseudo transparency disabled

!ALLY!62=01; one-trigger method (with count byte)

!ALLY!62=02; two-trigger method (default)
