Fix Missing PDF Files When Batch Printing with Acrobat PDF Printer
Question details
The user experiences missing print jobs when sending hundreds of files to the Acrobat PDF printer.

- Product
- Adobe Acrobat PDF Printer
- Device & OS
- not provided
- Scenario
- Batch converting hundreds of files into PDFs using a virtual PDF printer.
- Observed behavior
- Several files are dropped from the print queue, and pausing or restarting the printer does not successfully convert all the queued jobs into PDF files.
Ensure your computer has enough free memory and storage space to handle large print queues, as processing hundreds of files simultaneously can consume significant system resources and cause the spooler to stall.
Allow Uninterrupted Processing and Update Acrobat
Prevent print spooler errors by letting the batch job run without pausing and ensuring your software is up to date.
Interrupting a large batch queue by pausing the virtual printer can disrupt the conversion process, leading to dropped or missing PDF files. Letting the process run uninterrupted minimizes the risk of system timeouts.
Open Adobe Acrobat, navigate to the 'Help' menu, and select 'Check for Updates'. Wait for the latest patch to install to ensure bug fixes for the PDF printer are applied.
Confirm the file types you are attempting to print. Ensure there are no corrupted files or highly complex existing PDFs that might cause the printer to stall.
Send your batch of files to the Acrobat PDF printer again.
Let the entire conversion process finish completely without clicking 'Pause' or manually restarting the print spooler, ensuring every queued job is processed.

Clear the Windows Print Spooler
Clearing the print spooler resolves issues where corrupted queued files get stuck and prevent subsequent files from processing.
Use WPS Office for Reliable Batch PDF Creation
WPS Office provides a stable, built-in PDF conversion engine that natively handles multiple files without relying on the often-fragile Windows print spooler, preventing dropped jobs during heavy batch conversions.
- 1. Download and Install: Download WPS Office from the official website and install it on your computer.
- 2. Open the PDF Tools: Launch WPS Office, click on 'Apps', and navigate to the 'PDF Tools' section.
- 3. Select Batch Create PDF: Choose 'Batch Create PDF' or 'PDF to Word' depending on your workflow, and import your hundreds of source files into the conversion window.
- 4. Convert the Files: Click 'Convert'. WPS Office will process the files securely and stably without dropping documents from the queue.

Frequently Asked Questions
Why does the Acrobat PDF printer drop files during batch processing?
When sending hundreds of files to a virtual printer, the Windows print spooler can easily become overwhelmed due to memory limitations. Pausing the process manually or encountering an unsupported file type in the middle of the batch can cause the queue to drop remaining jobs.
Can I pause a batch print job to PDF?
It is generally not recommended. Pausing the PDF printer during a massive batch conversion interrupts the data flow. When resumed, the printer may fail to re-establish the correct sequence, preventing all queued jobs from being converted.
Are all file types supported for batch printing to PDF?
Most standard document and image formats are supported. However, if you include unsupported, password-protected, or corrupted file types in a massive batch, it may cause the entire printing queue to stall or silently skip the problematic files along with subsequent ones.
