I know activating a 4800 can be a drag if you haven't used it for a while - but don't worry about declogging it etc. You don't need to print.
Well, I have this thing about turning a printer on and then NOT printing...so I had to do a power clean and go through the normal gyrations of trying to get a friggin' printer up on my network-I can print using Epson AppleTalk pretty easy but getting a reserved address working on my DHCP server is a b!tch and using EpsonNet config on Win ain't easy either...
So, you want the good news or the bad news? I'm using Epson Win 5.5.3 driver over my Ethernet network. From the Photoshop CS3 Print dlog, I select the "Default" printer (yeah, ok, the 4800 is now the Default). In the Page Setup I select advanced, save setup under Mode: Custom and I've saved out a setting that is Luster paper, 1440, highspeed, Printer Color Management is off. Under Paper I've selected 8.5 x 11. Portrait under orientation and under Printable area Standard and Maximum are greyed out but I do select "Centered" in the setting.
In the CS3 Print dlog, I see both the top and bottom margins the same...I select Center then select Scale to fit media, then I hit print. A dlog comes up with my installed printers and the 4800 is highlighted. I click on Preferences to make sure the settings are correct...I notice that the Mode is NOT set to my custom settings, so I select from the dropdown...I click on the paper settings and yes, those are all as I set including the Centered button selected...I click ok, then click Print...it prints and then I measure both the top/bottom margins.
Top margin: 17/32nds (.53125)
Bottom margin: 18/32nds (.5625)
But. ..when I measure the entire page, the cut length is just a bit shy of 11" exactly. I don't have an accurate foot ruler (I was using a mic to measure the margins) but it looks to be about 1/32nds shy of 11 inches.
So, is +- 1/32 considered "Centered"?
Just for yucks, I printed the same image from Photoshop CS2....same printer, same settings, ie: Centered in the print driver and centered in the CS2 Print with Preview and also selecting Scale to Fit...results?
Top margin: 17/32nds (.53125)
Bottom margin: 18/32nds (.5625)
(seriously, same margin measurements)
So, the good news is I can print centered (pretty much if +- 1/32nds" counts) from Photoshop CS3 to _MY_ 4800. The bad news is that you don't seem to be able to.
Your milage may vary (apparently is is).
It's now 2:00AM Central and I'm outta here.
(ya see the lengths I'm willin' to go through for you guys....jeeesh and the crap I get)
:~)
P.S. BTW, just to confirm the Firmware on my 4800 is the current A01868 posted on 12/07/06
