Problem

Symptoms: When printing a PostScript file to an Apple LaserWriter with a Version 38 PostScript interpreter, "_t999" (where 999 is some number) produces an error message to the effect of "Error: _t number is undefined, etc." Then it clears out the rest of the job. This is not a problem on the new interpreters, but is a problem for the old ones. Earlier drivers which used a blank instead of a carriage feed worked fine. Solutions: The reason the driver is setup this way is due to VAX. When VAX uses this, it has a limitation of 128 bytes per line; if we only had a space after the _t then the line could be longer than this and anything after the 128 bytes would be lost. The problem is with the interpreter; the customer will need to get a new one to fix the problem. This problem can occur with any old PostScript interpreter, meaning an interpreter which needs a space rather than a carriage return following the _t code. We cannot change our code, thus we do not support these older printers. The only way to fix it is to have the customer get a new interpreter, thus updating their printer, and making it like a new PostScript printer.
