Printing Borderless at 42" width?

Borderless print ?
Set custom page as exactly paper size. Set borderless expansion to max. Select appropriate paper media type.

I thought maybe you have the paper size set to Landscape rather than Portrait. If not, then you might look at:

I did some searching on that site and it yielded the hlep below which may give you some help.


Issue: How do I set my printer so my printout fits the paper size I am using?
Solution: Use the recommended Print Area MP240

Printing Area To ensure the best print quality, the machine allows a margin along each edge of media. The actual printable area will be the area inside these margins.
Recommended printing area (dark blue):
Canon recommends that you print within this area. ()
Printable area (light blue):
The area where it is possible to print. ()
However, printing in this area can affect the print quality or the paper feed precision.

Note
Borderless Printing
By selecting the Borderless Printing option, you can make prints with no margins.
When performing Borderless Printing, slight cropping may occur at the edges since the printed image is enlarged to fill the whole page.
For Borderless Printing, use the following paper.
- Glossy Photo Paper "Everyday Use" GP-501
- Photo Paper Glossy GP-502
- Photo Paper Plus Semi-Gloss SG-201
- Photo Paper Pro Platinum PT-101
- Photo Paper Plus Glossy II PP-201
-Photo Paper Pro II PR-201
- Matte Photo Paper MP-101
Performing Borderless Printing on any other type of paper may substantially reduce printing quality and/or result in printouts with altered color hues.
Borderless Printing on plain paper may result in printouts with reduced quality. Use them only for test printing. You can perform Borderless Printing on plain paper only when printing from your computer.
Depending on the type of paper, Borderless Printing may reduce the print quality at the top and bottom edges of the paper or cause these parts to become smudged.

No Borderless option for custom paper sized. Borderless prints are only available for pre-define paper size like 8.5"x11", 4"x6", 5"x7", 8"x10", etc.

You must select borderless in the print options/preferences menu.
What program are you using to print and I may be able to help more.

Set your file up as a landscape, set your printer as portrait. Setup you width and height to be a half inch larger in each direction (unless you are doing borderless) and try with preview (so you dont waste time, ink & paper) see if this helps

Make sure the paper size is not set to US letter sheetfeeder borderless use just US letter. the borderless function slightly enlarges document content to ensure that it bleeds overthe edge. If your has a bleed, use in page setup - US letter sheetfeeder borderless - In the print dialog box click printer button which brings up a warning about using a different settings dialog box, - continue on to the r1800 print dialog box. about midway down is a pull down menu - choose expansion and adjust it to the lowest setting. if your printout does not bleed to the edge bump the expansion adjustment up 1 measure.

Work around solution is to trim paper to 8.25 x 11 inches and  setup a 8.25 x 11 custom size and then specify it each time you print. You probably can get by using the 8.5 x 11 setting on 8.25 paper but do not use borderless printing. Good luck on a very irritating problem.

So which OS are you using? 98, XP or Vista? Have you tried delteing the printer from your machine, downloading and then installing the latest driver from Epson?

Are you setting up a custom paper size each time? Check out page 91 of the 9800's user manual... it has a table of recommended custom paper widths for borderless printing.

you want to print borderless on a cutsheet media? you just have to select and 'cheat' the printer in the printer properties, in there choose roll on the paper source option then enable the cutter and choose double cut on printer's set-up menu on the panel, then it'll cut before and after the printing to make it borderless from top to bottom and from edge to edge. just be sure that the cutsheet media is long enough so that the printer can still hold the media as it finishes the printing or else it'll be a waste, cause the printer wont finish the image. and take note that the epson sp9600 has a limitation in printing borderless, it'll only print borderless on (12", 17", 24", 36:, and 44") media size only i think there's also 14". trust me it'll work, ive done it! :P
