If you are having trouble with slow printing – or there is an unusually long pause between pages – you may need to switch off your print spooler or print buffer. These two features were created to help the average job process without overloading your computer’s RAm, but we’ve seen that these can actually slow down or cause a Number Machine Pro job to fail completely.

The print spooler and buffer work by forcing a single job with many pages to process as if it were many single page jobs. This works fine for the average print job, but will often cause failure when you are printing a numbering job, especially if you are printing a PDF at the same time.

Luckily, it is easy to switch these features off.

Print spooler:

1)     Windows XP

  1. Go to “Start”, ,
  2. Right click on “Printers and Faxes”
  3. Choose “Properties,”  then choose the “Advanced Tab”.
  4. Check “Send directly to the printer” and then click “Apply” or “Ok”


2)     Windows Vista

  1. Go to “Start”, “Settings”, “Control Panel”, “Printers”
  2. Right click on the printer
  3. Choose “Properties”, “Advanced Tab”.
  4. Select “Send directly to the printer” and then click “Apply” or “Ok”


3)     Windows 7

  1. Go to “Start”, “Devices and Printers”, right click on your printer
  2. Go to “Printing Preferences” then choose the “Advanced Tab”.
  3. Select “Start Printing Immediately” and then click “Apply” or “Ok”


Print Buffer

The printer’s buffer is what allows you to access many higher functions such as duplexing, reverse page order, collating, etc. Using these features while printing a large numbering job can cause overload and failure. We suggest you do not attempt to use these features when printing from Number Machine Pro.

Sometimes, your printer will allow you to switch off the buffer. Every printer has different ways to do so, and you will need to consult your printer’s documentation to learn the best way to turn the buffer off.
