help with a variable...

[estierkol]

Hello to all the community, I would ask if I can help in a case I have to do with postscript,

I  wanted to know which variable is the postscript occupied when you print  multiple pages on one sheet, and I need to save that data to implement a  system of printing,

will be very helpful.

greetings.

What you are trying to accomplish is something called imposition. There is no variable in PostScript that automatically provides such a function. There are any number of ways of writing PostScript for a print job to accomplish such imposition or n-up printing. None involve simply setting a variable someplace. Strongly suggest you learn the PostScript language if you need to pursue this further.

Thank  you for responding Dov.

I explain a little, I'm developing a program  where he studied printing, postscript and rescan the number of leaves by  counting the string "%% page" and the number of copies of another  string "%% BeginNonPPDFeature: NumCopies "then  I need to know the other name of the string, where does the number of  pages in a single leaf, I hope I have explained, it is to know when a  command to print multiple pages on one sheet, not if you say this is called taxation.
I will be very attentive to your answer.
Greetings.

(1)     The lines beginning %% are comment lines in the PostScript program; they are not PostScript code itself and you cannot rely on them.

(2)     There is absolutely no available command in PostScript to print multiple pages per sheet.

mmm  I see, but I've used those lines commented and I have not had any  problems in recovering the data, in this case is the number of printed  pages, with a "for" travel the PostScript file and a counter to count  the string "% % page: "and so I have the number of  pages printed, and multiply with the data it gives me"%%  BeginNonPPDFeature: NumCopies "in the case of printing multiple copies  of a document, and so I have the total of printed sheets.

When  I send to print multiple pages per sheet or more slides on a sheet, I  can not see how that action and executes postscript is what I need to  finish my printing system.

Greetings.
