#164539 - Questions of definition
Responding to: ???'s previous message
One thing that should be cleared up right away. The O/P said he wanted to "print a graph" and didn't say he wanted to "print graphics." What he really meant is somewhat clouded by the possible "language problem" that's come up from time to time.

Another item that should be dealt with is, "What is the format of the source information?" This information comes from somewhere and has to be transformed from whatever format it uses to the bit-mapped graphic format that the printer can produce. The range of complexity of this task can vary from simply converting serially-input-to-parallel-output bitmap data to vector-to-raster conversion, scaling, and rotation of the information to fit the paper.

The size of the task for the 805x can't be estimated until this is known.

It's likely, BTW, that we've lost the O/P because he's figured out that the task is unmanageable from his standpoint. It would be wise, I believe, to wait for input from the O/P before dedicating any further bandwidth to this matter.

How to print graphs on a printer at centronix port by 8051            01/01/70 00:00      
   Assume nothing!            01/01/70 00:00      
      Specifications donot provide protocols            01/01/70 00:00      
         So you need the technical specifications!            01/01/70 00:00      
            Its a low cost Standalone system            01/01/70 00:00      
               Google            01/01/70 00:00      
         the protocol            01/01/70 00:00      
            some links            01/01/70 00:00      
         The signaling protocol is well-defined            01/01/70 00:00      
            Actually quite simple to use a matrix printer.            01/01/70 00:00      
               Questions of definition            01/01/70 00:00      
                  A graph normally requires graphics            01/01/70 00:00      
                     Indeed, but one is a subset of the other.            01/01/70 00:00      
                        You would do banded output            01/01/70 00:00      
                           suppose the data is presented in portrait format ...            01/01/70 00:00      
                              Band size doesn't matter so much            01/01/70 00:00      
                                 It only feeds in portrait format            01/01/70 00:00      
                                    No            01/01/70 00:00      
                                       You're right within the scope of your thinking            01/01/70 00:00
