Hi All.
I am running a 7900 with Piezography inks on a Mac, so using Print-Tool and qtr.
After getting everything set up, I've run into a problem where my print size is constrained by the "Paper Handling" tab in the print driver.
I set my paper size using the "Manage Custom Sizes..." dialogue, and send to the printer (for example, 600mm wide). However when it gets to the printer it is only printing about 210mm of the image width, and cropping the rest of it.
I eventually discovered this is being governed by the "Paper Handling" tab. There is a drop-down option for "Destination Paper Size:", and two check-boxes for "Scale to fit paper size", and "Scale down only".
When the boxes are unchecked, "Destination Paper Size:" is greyed-out, and defaults to "Suggested Paper: US Letter". This setting takes effect whether the check-boxes are selected or not, and limits my image size to US letter dimensions.
When I check the boxes and select a different paper size, that governs what size I am able to print to. There is no choice to make a custom size in that dialog, so in order to print as wide as possible, I have to choose "24x36". This results in my image (if smaller height than 36") being centred in the middle of the 36", and wastes a lot of paper. It also means I can't print larger than 24x36.
I'm not sure if it makes a difference or not, but this is using roll paper, not sheet. Roll paper is confirmed in both the physical printer panel and the QTR setting.
I have tried resetting the default paper size in the "Printers & Scanners" tab of system preferences, but no difference. I have tried reinstalling QTR (using Install7900-ProK4.command), but no difference.
Any ideas what is causing the "Paper Handling" tab to hijack my custom print sizes? I've never come across this sizing issue with other printers (colour 7900, 9800, Canon iPF8100) where the "Paper Handling" tab has any effect. I've always ignored it in the past.
Please help! I'm tearing my hair out!
