PDF file format processing: Using Ghostscript dll cannot do batch process

[abd]

Working in PDF file format processing by using Ghostscript, gsdll64.dll, cannot accomplish multi-page PDF file task by use of batch process.
Only do such for 1st page then quit.. Thanks in advance

When you perform a batch scan, each scan is appended to the file on disk. What you see in IrfanView when you have finished scanning is just the last page. Open the PDF file from disk, either in IrfanView or in a PDF viewer to see all of the pages.
