Hi I have used Photoshop for many years for making photo graphics, and I have enjoyed using the application. A couple of months ago I bought a new printer, Epson ET 8550, and until now I have primarily made pictures of size A3+ (329 x 483 mm) and just printed them I full size with good results. Right now I make pictures of size 30 x 40 cm and want to print them on A3+ paper in the exact size, but the resulting print has a different size. Because of my problems, I have made the following 3 tests. I want to print a Picture of size 30x40 cm. So I create a PS document of that size. The only content of the picture is a thin frame made as a Select (CMD+a) and an inside 2 px black stroke. In the print menu I select “Super B/A3 borderless” and Paper Type Premium Semigloss. The measure of the printed frame is 30,5 x 40,8 cm.I suspected the choice “borderless” to be the reason why the resulting frame is larger than expected. Next I print the same document, but now without “borderless”. The measure of the printed frame is 29,3 x 39,0 cm.I make a new document of size 20x30 cm and I print it with the same print parameters as in test 2. The measure of the printed frame is 19,5 x 29,3 cm. So none of the prints are correct, and I don’t understand it :-(. I couple of days ago I made a similar test print on A4 paper, where the document size was 10 x 20 cm. This time the right frame size was printed. As a last thing, I did as in test 3, but on A3 gloss paper instead of A3+ Semigloss. This time the resulting frame has the right size. To me it seems to be a problem with the A3+ format. But who is responsible, and how to fix it? I hope somebody can help me. Steffen Dyhrberg

Hi

I have used Photoshop for many years for making photo graphics, and I have enjoyed using the application.

Right now I make pictures of size 30 x 40 cm and want to print them on A3+ paper in the exact size, but the resulting print has a different size.

Thank you for the fine detailed list. I have done it all and I am now waiting for answer from Epson 🙂

@Steffen Dyhrberg Please share the solution here - if Epson give you a fix

You could also try this:"

On your Mac, choose Apple menu System Preferences, then click Printers & Scanners
Press and hold the Control key as you click in the list at the left, then choose “Reset printing system” from the menu that appears.
After you reset the printing system, the list of printers in Printers & Scanners preferences is empty.
Reinstall the print driver, only from the manufacturer, not Apple.

Also (for both Mac and Win) take a look at the following article and check if that helps:

You may like to re-install the printer drivers to check if that makes a difference?

Here is some general Adobe [Mac and Win] info on printing problems,
https://helpx.adobe.com/photoshop/kb/troubleshoot-printing-problems.html

Simple reset for Photoshop printing: hold the space bar when you open the print window. It resets the print dialogs - deleting possibly corrupt print metadata in the file.

On most printers, selecting 'Borderless' printing results results in a slight scaling up of the image. That is to prevent white edges showing if the paper is slightly misaligned. I don't know about their Mac drivers but on Epson's Windows drivers, when choosing borderless there is an Expansion option, which can be set to Autoexpand or Retain Size. Retain size stops the scaling but at the risk of those white edges showing.

This is why many commercial prints are made with a bleed area, i.e. an extra area of image around the print, which is trimmed off when the paper is cut to final size. That allows for any misalignment in the printing process.

Thank you Dave for your explanation to the use of borderless printing.

In my test 2, I don't select borderless, and the print size is still not exact as it is when I print on A3 or A4 size paper. So I still have a problem and as far as I can see there is not a posibility to set detailed options as you show me.

But thank you for a fast response.

It sounds like there is some scaling going on within the Epson print driver. Unfortunately, as a user of a different Epson printer (SC-P5000) on Windows 11, I am limited in what I can test here.

Hopefully, someone with an Epson printer on a Mac may be able to help.
