PDF Printing To Network Printer Slow

Hello Experts,

I am stuck on trying to figure out why my PDF documents expand when I print them. When I right-click the PDF document, it shows the size as being 5.5MB. But when I print it, it shows the document being 23MB in print manager.

Can anyone tell me why the file is growing when I print? I've used PCL and PS drivers. I tried to print on multiple printers with same results. This only happens on certain PDF documents mostly with images embedded.

As Todar and velbaglf have already mentioned, this is because the printer (probably) doesn't natively understand the PDF format (although a few modern printers do), so the printer driver has to convert the objects in the PDF document into equivalent objects in the target Page Description Language (PDL) - usually one of PCL5, PCL6 (aka PCL XL) or PostScript.

... and the formats of these printer languages tend to be at a lower-level, and rather more verbose than the original source document formats.  

As regards images - most images for screen use are captured at 96 dots-per-inch resolution (or perhaps only 72 dpi on older systems, or 120 dpi with high-resolution).

But most modern printers use 600 dpi (or higher) resolution, so raw images require more storage space to describe them, although compression techniques can reduce the size.

For example, a monochrome one-inch square image at 96 dpi would require 9216 bits, or 1152 bytes.
The same source image, converted (by the driver) to 600 dpi, would require 360000 bits, or 45000 bytes, without compression.

When printing PDF documents, PostScript is quite often the best choice of driver, since the two formats are fairly similar (both were 'invented' by Adobe).

Hi katedrum,

It is expanding to a larger size since the printer does not speak PDF it speaks PCL and PS (and maybe even PCLXL). the spooler (print manager) has to convert it to the language the printer understands before it sends the data to the printer.

 Also, when a file (PDF or other) has images, those images are much larger when converted to the printer language so that it will print with better detail than that which is needed to display it on a PC monitor.

Hope this answers your question.

You might try a different version of Adobe Reader.  If you are using the current version of Adobe Reader,  version X, there have been printing issues reported with it.  Try going back to Adobe Reader 9.  

Now, if you are using Adobe Reader 9, try Adobe Reader X and see it it changes anything.  They did make enhancements to printing and it might help with your documents.

Good luck.

Actually I tried using 8.1.7 Standard & 9.1.4 Standard. Both with the same slow printing. I guess I'm trying to figure out why does the PDF document say that it is one size and when I print, it is like 4 times more than the file size? How can I prevent the file from expanding?

This is a driver issue.  It may or may not mean anything is wrong with your driver, but that's just how it works.  Some work better than others of course, as long as they are compatible with your printer model.

Some things to try would be to install the printer with a local TCP/IP port and test.  Also, when printing a PDF, File > Print > then choose 'Advanced' > put a check in the box for 'print as image'.
