Qimage media type and print driver type mismatch

[sharadn]

I have been printing with Qimage for many years. Recently I purchased an Epson P900. When I set the media type in Qimage it shows (for example) RR Aurora White 300, but when I go to the actual printer driver it shows the media type for Canson Platine: cifa_p900_platine310_p_bk. Which one is actually control, Qimage or the driver?
I also print with an HPZ3200 and I understand that there are issues communicating between Qimage and the print driver which has driven me nuts for years now but I did get some help here and on the DPR forum.

I thought there were no issues like this with the Epson printers. Please clarify. See the screen shots

I posted this question on Mike Chaneys forum. See his response below:

Unfortunately both the P900 and Z3200 are extremely buggy drivers. Since RR Aurora White 300 is not a standard Epson media type, I assume you added custom media types using the Epson tool? If Qimage and the driver don't align on media type it means the driver has a corrupted media type table and is not reporting the proper media types to Windows. This can sometimes happen when you use the Epson media tool to create new media types and the tool does not properly update the media types (and indices) in Windows or crosslinks some media types so that multiple media types have the same numeric index. In a case like this (where only the driver can see the correct custom types), you have to select the media type in the driver. Don't try to change media type in Qimage if you are having this problem because the driver has given Qimage a bad media table (index).

As far as I know, this is only an issue with the HP Z series printers and Epson P900.

Unfortunately for me these are the two printers that I have and for the P900 I am sure that there are thousands of others.
