Counting Pages in PCL 6

Counting Pages in PCL 6

Counting Pages in PCL 6

(OP)
Hello everybody,

we want to count the pages in a PCL 6 or PCL XL file, respectively. PCL 5 or below is based on ASCII text, so parsing for some commands which indicate a page switch is no problem. PCL 6 is a binary stream where the size of the commands and parameters is not fixed. How to parse this?

Does anybody know where I can find some information and some examples about PCL 6 and rules for building the binary steams?

Thanx a lot

RE: Counting Pages in PCL 6

From my limited knowledge of PCL6, I would say that
you have a formidable task in front of you. The
EndPage command in binary is simply 0x44, but as that
is the letter "D" it doesn't get you very far.

I would suggest that you contact HP in Europe and
see if you can get the PCL6 details.

Hi jlasman,

thank you very much for your help.

I already have the technical reference of PCL 6 from HP, but as you said the codes for the commands are readable letters. What's before a command (compareable to ESC) and what's behind a command depends on several things.

Well, what can help a lot is an example for building a command sequence. This will make it much easier for me to understand the documentation. Does anybody has such an example?

Thanx a lot.

RE: Counting Pages in PCL 6

What I have seen is very similar to an Editor/Assembler
for machine code.

The PCL6 code is written in its assembler language
and is then "assembled" into PCL6 object code.

There is a program called "jetasm" that I believe
can also disassemble the obect code. If you could
disassemble and then count the EndPages you might
have it.

Again, contact HP.

Hi Pascal

Did you find a solution to you problem on how to count the pages in a PCLXL file?

Regards

RE: Counting Pages in PCL 6

As Jim states, you'll need to parse the stream using the JetASM dissassembler, or similar.

I wrote one some time ago; an extract from the output (if it will fit in the width here) shows the format (use this in conjunction with your PCL6 Technical Reference document); sorry if it's a bit long ( I don't know the rules/conventions for code snippets/samples in these forums):

RE: Counting Pages in PCL 6

Our PCLTool Program or PCLTool SDK can count PCL XL pages.

We provide the page count in the .log file generated when you try to view or convert a PCL XL file.  We currently do not view or convert PCL XL, just PCL3-5e.  Our next release adds PCL5c.  And, we have a beta PCL XL text extraction tool, then also counts pages.
