This is the result of running the program on the file 00025.spl from above: I was able to obtain documentation about CPCA by signing up for the Canon Developer Support Program at the following URL:Īfter reading this documentation, I wrote a program to remove CPCA codes from spool files. I tried a similar solution for the files generated by "Canon iR-ADV C5235/5240 PCL6", but unfortunately was not successful.ĮDIT (): It seems that the binary sequences are CPCA codes. After removing these sequences, we were then able to convert the files as normal. There were binary sequences beginning with $CDCA10 and ending with $FFFF000000000000000001 at various positions in the files. Incidentally, we had a similar problem with Postscript files generated by the "Canon iR-ADV C5235/5240 PS3" printer driver.
We asked VeryPDF and they told us it is not a valid PCL file.Ĭan anybody tell me what exactly is invalid about this file? Is there any possibility of converting it to valid PCL or otherwise extracting usable data from it? Attempting to open 00025.spl using other PCL viewers gives similar results.
As an example, the following SPL file results from printing out a single page in notepad with the word "something" on it:Ĭonverting 00025.spl using pcltool.exe results in a 70-page PDF with a row of garbage characters at the top of each page. However we are having trouble with SPL files generated by the printer driver "Canon iR-ADV C5235/5240 PCL6". For SPL files in PCL format we perform this conversion using pcltool.exe from VeryPDF, which mostly works fine. In our software we need to be able to convert SPL files which printer drivers write to the C:\Windows\System32\spool\PRINTERS folder to PDF files.
