Question

Is Postscript Leading and Trailing Edge Manipulation Possible?

I am troubleshooting sending postscript to a Ricoh Pro 8110. The postscript is sent to the printer via LPR command. I am trying to print a barcode as close to the edge of the right side as possible.

The problem I am having is that even though the postscript appears fine when viewing it with GSView or other postscript viewers, when it prints on the Richo printer the left edge of the printed output is truncated, and the right edge has a margin. So the Leading Edge is too small (on the left) and the Trailing Edge (on the right) is to large. Its as if the rendered postscript does not line up on the page properly. I have checked that the page size is 8.5 X 11. Here are my questions:

1. I am thinking the problem is more likely an issue with the printer, than it is with the postscript. Is this correct? If so are there any particular printer settings I should look at?

2. Is there any postscript commands that will "shift" the entire content to the right or left? I would like to see if there is a way to cause the rendered postscript to shift to the right about 4mm.

Here is a very basic postscript file I have been testing with that is experiencing this problem on the Ricoh printer.

I sent Sample.ps to another printer and it had about 1/8 inch of white space on the top and left and 3/8 inch on the right. Characters were clipped on the left and right sides. My guess is the media is being grabbed by rollers on the right side and the rest of the non printing area is to avoid writing off the media.

A simple test to show the unprintable are so you can rule out issues with Sample.ps

As a side note you could rotate the page 180 degrees to get more of the barcode.

Would you mind explaining this further? why would rotating the page 180 make a difference?

The rotate would place the barcode on the other side away from the non-printable area. You could also scale the page

so nothing is clipped off.

Most all toner-based have an “imageable area” that is smaller than the full physical page size. This can often be up to 0.25" (but usually less) on each side of the page. The device's engine simply won't print in those areas. Printing to the edge is most commonly referred to as “bleed.”

The way bleed is accommodated for by most professional printers (not only toner printing, but offset, inkjet, etc.) is to print on paper that is larger than the final desired resultant page and trim the paper down to that final page size.

Otherwise, you pretty much need to live with this issue.

I suggest you confirm the imageable area issue directly with Ricoh. This is not really a PostScript or an Adobe issue.

Dov,

Thanks for the response. I am aware of the printable area. However, I do not understand what you cause the rendered output to be truncated on the left side when there is still space on the right side. I have inserted an image of one of the tests I sent to the Ricoh printer.

If you post the PostScript file for us to look at, I can try to see what's going on.

Dov,

thanks for your help.  I could not find a way to attach the postscript. to this forum. But you can access it here:
