Abstract

Disclosed is a method to provide printer page formatting within a file composed of "snapshot" images. "Snapshot" is a term used to indicate displayed data for the ASCII Terminal Emulator which is a part of IBM Operating System/2 Extended Edition. A file containing these snapshots, without any page formatting control, is less usable when printed. The problem of printing across perforations on continuous-forms paper is an example. The ASCII Terminal Emulator allows the user to specify the length of paper to be used to print a file containing snapshots. Using this information, the ASCII Terminal Emulator formats the data, with standard ASCII control characters, to provide a printout compatible with the type of paper or forms used. The formatting criteria is as follows: 1.

Page Formatting of Screen Save Data

Disclosed is a method to provide printer page formatting within a file composed of "snapshot" images. "Snapshot" is a term used to indicate displayed data for the ASCII Terminal Emulator which is a part of IBM Operating System/2 Extended Edition. A file containing these snapshots, without any page formatting control, is less usable when printed. The problem of printing across perforations on continuous-forms paper is an example. The ASCII Terminal Emulator allows the user to specify the length of paper to be used to print a file containing snapshots. Using this information, the ASCII Terminal Emulator formats the data, with standard ASCII control characters, to provide a printout compatible with the type of paper or forms used. The formatting criteria is as follows: 1. The number of snapshots per page is always

maximized. Each snapshot is always 25 lines long.

2. The minimum number of blank lines, separating

snapshots, is always one.

3. Given a specified page length P, only a whole

number of snapshots (N) will be formatted. N is

the integer portion of P/(25+1).

4. Snapshots are separated by the same number of

blank lines (n) to fill up a page (n=(P-N*25)/N).

n is always rounded to an integer and has a

minimum value of one. All remaining blank lines,

if any, are added to the bottom of the page.
