Default PDF to JPG loses edge on printing

The title more or less says it. To explain: I have a preloaded PDF document I have to modify each week (no problem there) and then email somewhere. A PDF file is just much too big to email (well known) as it would takes ages to load and send. So, I have used various (free) converters to change it to a jpg file. Looks good on my PC but when printed at the other end it always has some of the left hand side cut off. I have tried making a new file with a physically smaller picture (larger margins) and on my PC it looks good again with a blank border all round it. Printing it though still has the same result. I have seen the term "bleed" but that seems a bit too technical for me. Anyone help please?

If the jpeg image file displays correctly then the problem is almost certainly with the printing. It could be caused by print setup. Relevant settings might be centering or right-aligning the image, or zooming the image to fit the page.

What happens when you print it using the same method?
If you added a border or increased its size in the image file then it should produce a consequent change when printed. Even if the print output is being centered/right-aligned on the page it would still look different.
What is used to print it at the other end? Does it have a preview and if so does it print as previewed?

Bleed means printing beyond the area that will make up the printed page. The printer then trims the sheet to produce the printed page. They often use large guillotines to do many sheets at the same time.

Bleed is not normally an option in home and office printing because most printers don't print to the paper edge. Or if they do, they don't print to all edges. Also we don't usually trim our printed documents.

Thanks for reply Remah but I think we may be talking at cross-purposes. I am pretty good with adjusting printing settings etc. and I don't think the problem lies there. It happens ONLY with pdf files that have been converted to jpg or jpeg. If I use (for instance) Photoshop to convert, the resulting image on my screen looks fine in the Photoshop display or any other program I use to view it. When I print however it has lost some of the side both in print preview and on the actual paper. This happens even if I reduce the whole size of the document so it has a wide border around it. The border will be there but part of the document will be lost. I am sure this is a result somehow of converting from pdf to jpg. I remember reading about it somwhere (can't remember where now) but I didn't see any way to fix it.

Update: The cutting off depends on which program I use to convert the file. However, if I use a converter which does NOT show cutting off when I open it then, as you suggest, the problem IS with the printing options. Not all programs give you a preview or chance to change the settings. However, on ones that DO give this option (MS Photo Editor) then I find unticking "fit image to frame" or similar solves the problem.
Thanks again.
Jim.

Adding to what I said earlier, I did some searches and confirmed that there is no bleed feature in the JPEG file format so any problems would not be from that source. That means it is either the conversion process or the printing process leaving blank areas.
  • many PDF to JPEG converters do take account of the PDF bleed settings so the conversion settings need to be set to match what is wanted.
  • many people have similar problems printing their images without having converted them from PDF. It's almost always the print settings.
I found a nice little tutorial on bleed Artwork Yays and Nays for those who provide designs to be printed by Moo.com. The principles apply to images in general.
Here's a tutorial on how to set the bleed settings in Photoshop, Illustrator and InDesign.
