so I've been pulling my hair out for 2 days & nights now trying to figure out why I couldnt print on custom paper sizes - I've just now hit the "help" icon in the print dialog box (so simple I didnt ever think to read through the steps set out!) and found this:
"Creating a custom page size
If you want to print on unusual size paper, such as an odd-size envelope or card, you may be able choose the paper’s size from the Paper Size pop-up menu. To find the Paper Size pop-up menu, choose File > Page Setup, if available. Otherwise, choose File > Print.
If you can’t find the size you need, you can create your own custom paper size.
To create a custom page size:
Open the document you want to print.
Choose File > Page Setup, if it’s available. Choose Page Attributes from the Settings pop-up menu, and then choose Any Printer from the Format For pop-up menu.
Choosing Any Printer ensures that your document can print on any printer that supports the paper size you select.
If Page Setup is not available, choose File > Print.
If the Print dialog contains only two pop-up menus and some buttons across the bottom, click the disclosure triangle beside the Printer pop-up menu.
Choose Manage Custom Sizes from the Paper Size pop-up menu.
Click the Add ➕ button.
Type a name for the paper size.
Enter values in the Paper Size and Printer Margins field."
All I had to change was the "any printer" setting from my (konica minolta) printers name to "Any Printer"!! now my custom paper sizes are printing fine and dandy!! phew!!!!!!!!
I know this isn't the exact prob you're having, but try the help in the print driver and follow the steps set out - it worked for me!
