epson pm-a850 printer malfunctions
Last modified: 2007-11-30 17:11:39 EST
Description of problem: Selecting the obvious drivers for the epson pm-a850 does not produce useful results. Either the PM-850PT or the PM-970C will simply feed paper until you shut the machine down. Setting up queues for both at the same time results in printing almost working with the PM-850T driver. The printable area will print, but the page will not complete. (No final form-feed-type-action, the paper just sits in the printer as if waiting for something more to be added.) Version-Release number of selected component (if applicable): How reproducible: Every time. Steps to Reproduce: 1. Set up queue. 2. Select driver. 3. Save printer setup. 4. Try to print. Actual results: Either the paper just feeds forever without printing, or the print stalls and the fails to feed. Expected results: Well, you know, a printed page that ends up in the printer output tray. Additional info: The scanner works with Kooka with the PM-970C driver selected, but not with both.

There doesn't seem to be a driver for this particular printer.
I should have mentioned, I suppose, that I have had this printer running with one or the other of the above mentioned drivers on FC4, and that it quit working with FC5. (Scanning on this beast is much better with FC5.)
Okay, I dug out the manuals for this printer this evening, to see if it is a 24 or 48 nozzle printer, and I find that I had dug up, two years ago, that it is assumed to be the domestic (in other words, Japanese home market) version of the RX600 or RX610. So I tried the Epson Stylus Photo RX600 series drivers in the setup, and it works quite well. I can't judge all the differences between RX600, RX620, and RX630, but I do note two things -- Without Gutenprint installed, only the RX600 non-foomatic PPD worked, edge to edge on all edges, but it failed to eject the page at the end. With Gutenprint installed, and after testing some of the other printer/driver combinations, it ejects, but the trailing edge seems to get the last millimeter or so clipped. I think it was the RX620 with the non-foomatic simplified driver, but one of the combinations printed the trailing edge pattern two centimeters before the trailing edge of the page. Sorry for the noise.
