Thanks. The page properties are not entirely correct. The length is ok (669 = 675 minus 2x3mm margin), but the width shows 352, which is the print width, not the page width (which is 431.8mm).

I have set "sheet" as the source. I'm assuming Epson has no problems with this page size with the sheetfeeder as input. Maybe I should have chosen "roll".

I'm on 2017.114. Printer is an Epson SC-P800. I have defined a custom page size of 431.8x675mm (in the Epson driver). I put one tiff on the page and specified custom size with a short dimension of 352mm. This results in a long dimension of 581mm. When I put the cursor on the image, it shows the correct size, when I put the cursor on the page outside the image area it suddenly says 669.1x352. When trying to print something tries to fit the image (probably thinking it is too long) which results in a height of around 308mm. That's one expensive piece of baryta ruined. Has anyone noticed something like this before? Am I doing something wrong? Don't want to waste more expensive paper. In the Epson driver I did notice a box "optimize enlargement" which was ticked. Could this be causing the trouble?

My R1900 also has no problems whatsoever with 2 year old inks (original Epson). I once had a severe clog of the cyan channel. Cleaning cycles did not help, using cleaning catridges (filled with IPA judging by the smell of my prints) helped a bit, and it was finally solved by soaking the sponge with distilled water and letting the printer rest for a few nights that way (turned off/heads parked).

It seems that indeed Comodo internet security was the cause of the problem. Disabling it did not help, but updating to version 8 (from 7) did. As I like living on the edge, I also updated QI to 110  . Also works fine!

Thanks everyone for help and suggestions!

When I reinstall 2014-135 everything works again and all printers that Windows reports are available. I tried using the qimagepr.ini file that 2014-135 creates with 2015-109 to no avail. Resetting printer or all program settings also does not work. So something strange is still going on.Disabling the anti-virus (Comodo Internet Security) does not help. Installing application data on a different drive did also not help.

Oh well, off to bed, I'll give it another try tomorrow.

That is what my devices and printers looks like, just with different types of printer.

this is more what part of the file looks like. I have deleted it, but the problem remains and no new file is created.

And when I check the Windows contol panel, there are several printers being reported. Canon Pixma iP4000 (default printer), Epson R1900 and a Canon MX920 (network) printer.

I have the Qimagepr.ini file in 2 locations: c:\programdata\ddisoftware\qimage and c:users\all users\ddisoftware\qimage. Or is this just 2 names for the same directory as the contents seem to be identical?

Anyway, the contents of the file is only partly readable (lots of strange characters), but the name E P S O N   S t y l u s   P h o t o   R 1 9 0 0   S e r i e s appears a few times. The file is 2567 bytes, that seems a bit much for 1 line? Corrupt file?

After re-installing 2015-109 the error remains. The qimagepr.ini file is the same as before, 2567 bytes and lots of strange characters and has the date of 3 december 2014. The qimage-u.ini file is readable however and somewhere has a line that says "EPSON Stylus Photo R1900 Series".

Thanks for the replies, I will try some of the suggestions this weekend and report back. I doubt the cable is the cause. Why would only QI 2015 have problems with this cable and no other software for the past 6 years this printer has been connected with this cable?

Interesting is that QI queries for printers at startup of the program. This might explain something as sometimes my printers are turned off while I start editing an image and only turned on when I want to print it. Although the printers were turned on when I uninstalled 2015.109 and installed 2015.105 and 105 also reported no printers.

I have the same problem with 2015-109. Print spooler is active and started automatically. No network printers, just the ones connected to my pc with USB. Disabling Malwarebytes anti malware has no effect. Other software does recognise the printers and can use them.

I uninstalled 2015-109 and installed 2015-105 (latest version of previous license period, but never used): same problem. I then uninstalled 2015-105 and installed 2014-135 (latest version that I actually have used): no problems at all. Recognises the printer straight away, and produces a perfect print.

So I would say there must be some problem for some users with the latest versions, maybe something that has changed between 2014 versions and 2015 versions? Any help pleas, as I'd like to use the latest version.
