Ammendment: DVI limits only for devices which may support it (S2) Ammendment number: 06 Submitted by: Joachim Schrod Date: 02 August 1990 Status: RO Currently says: As a rule, {\tt DVI} drivers should be able to interpret any {\tt DVI} file which falls within the following limits. These specifications are a {\em minimum\/}; good drivers will probably be able to handle {\tt DVI} files exceeding these limits ({\tt DVI} files which exceed the limits are likely to be rare, but might still occur). Change to read: As a rule, {\tt DVI} drivers should be able to interpret any {\tt | DVI} file which falls within the following limits. | If these requirements may not be realized due to limits of the | output device they should be fulfilled as far as possible. Besides of | this exception the specifications are a {\em minimum\/}; good drivers will probably be able to handle {\tt DVI} files exceeding these limits ({\tt DVI} files which exceed the limits are likely to be rare, but might still occur). [vertical bars indicate the changed portion] Reason for change: There exists popular devices on which it is impossible to realize the required limits. It is nonsese to say that these devices may not be used for TeX output any more. Example: Suppose you have an HP LaserJet+ with 512 KB of memory, leading to 390 KB usable memory. A driver for such devices should also support nearly-compatible printers (old Kyoceras), therefore it may not use character codes between 0 and 32 resp. 128 and 159. If a page with 20000 different characters shall be printed these characters may neither be downloaded (only 16*191=3056 chars) nor may they be printed in bitmapped form because you cannot print a full page bitmap with this printer. Furthermore this device cannot print characters in the size 600 to 800 pt for the same reasons.
