The Graveyard - Products No Longer Supported => Other D-Link Products => DPR-1260 => Topic started by: kvon on December 16, 2008, 03:09:29 PM

Actually, it's an intermittent problem. Sometimes the prints come out at a speed normal for the printer, other times... Put it this way - I did a 5½ x 8½ print, normal photo print quality, and it took 11min 37sec. I did the exact same print over the USB connection - less than 30 sec.
Found a thread on another forum about setting the TCP/IP port protocol from Raw to LPR, and to enable the byte counting. (Side note - I haven't found any explanation about what this means or what it does, if anyone could enlighten me I'd appreciate it). At any rate, this didn't seem to work... Still, it's like every other print goes at this snails pace print speed.
I'm running Windows XP. Also, I see that the R1800 is on the compatibility list for this print server, but not the R1900 (too new).
Any ideas anyone??
Thanks...
-
Is the print server connected wirelessly?
-
Yes - wireless print server. Would it be useful for troubleshooting to try it hard-wired?
-
yes, see if the lag is still there.
-
OK - I wired the print DPR-1260 to my computer through an ethernet cable. Seems that it functions just fine in that configuration.
So what does this mean? Please tell me that the answer is something other than "you gotta use it hard-wired"...?!
Thanks...

Have you tried to update the driver for you wireless adapter?
-
what router are you using as well?
-
By "wireless adapter", not sure if you're referring to the print server, or my wireless card on the computer? The print server does have the latest version of firmware (v1.24). Not sure about the card - would that make a difference? I'll check...
The wireless router is a Linksys WRT54G.
-
Yes the wireless card in your computer.. check to see if there are updated drivers for it.
-
how far away form the router is the dpr-1260?
-
The router is no more than 30 feet away from the print server, going through a wall and a coffee table. Don't have issues with any other aspect of the wireless however. I actually have 2 printers hooked up to this print server, the other one being an hp 1320 laserjet. No problems there whatsoever.
FWIW, I downloaded the latest version of the driver & configuration software for my (Netgear) wireless card. I have doubts about whether the device driver has been updated to the latest version however, and am in contact with Netgears' tech non-support about it. That's a "whole 'nother story" in itself - I'd love to rant but that's for another forum I suppose. Anyways, will post when I've got it straightened out.
Thanks everyone, for all the input.
-
OK, I've confirmed that I DO have the latest drivers for the wireless card according to netgear. As I write this I'm printing out a sheet with 2 5x7 photos on it, and it's been going for 21min now, still not finished. Anyone have any suggestions?
-
is the DPR rockin the latest code?
-
Yessir, Rocking - AND - a Rollin. Firmware version 1.24.
-
Update - just discovered that if I print in wireless mode, a file in text mode with just some simple graphics (a web page for example), it prints at the normal speed. So it's just the high res photos that are the issue...
-
My guess is data throughput via wireless. 54mbps real data rate of like 22 mbps, so a 4 meg file in hi-res is going to take a minute.
I'd hardwire it if you can.
-
I do appreciate the input, but if I have to hard-wire it, it completely defeats the purpose of having it in the first place. I would just run a USB cable & take the print server out of the loop.
I'm a little skeptical of attributing it to simple throughput overload. I may be wrong on these numbers(?) but I'm thinking 54mbps (b=bits?) is 6.75 MB/sec, or 405 MB/min. Like I said earlier, one photo I printed took well in excess of 20 minutes to print. Don't recall the exact file size that was sent to the printer, but they usually run 15-20MB. So a 20 minute print time for a file that size really suggests to me a malfunction of some sort.
Here's another clue that may or may not be significant... When it's in super-slow wireless mode, the pattern is that the print head can be heard to make a single pass over the paper and back, and then it will sit there for way too long, like 10-15 sec before starting the next pass. When it's working properly (through the USB cable), there is no delay at all between consecutive passes of the print head.
It may be that this combination (printer & print server) just isn't compatible, and truthfully, that was a calculated risk I took when I chose this model print server. Seemed like a good risk though, because the R1800 (the predecessor to my printer) is on the published compatibility list.
-
Are you running in RAW or LPR? Also the DPR is passthrough, there is no memory on it, so if your printer lacks an onboard pool flash ram, then the data would have to stream, wait for the printer to process it and then print.
I'm still blaming poor throughput. Here's a test. Hook a computer to the ethernet port of the DPR and test the throughput.
-
Already did that, there's no delay when it runs through an ethernet cable. (see post #5 in this thread). I think that disproves the throughput theory...?
-
Egg on my face, but good lesson learned... It was the phone! Had the print server and the cordless phone base unit right next to each other, like 3 inches apart. Read in the manual that this was a no-no (it wouldn't have occurred to me otherwise), so I powered the phone down, and voila! I did some minor rearranging, and now have them about 4½ feet apart - seems to be working fine. (FWIW - the manual specifies 2.4GHz phones as being the trouble makers, mine is a 1.93GHz, but close enough obviously).
-
Kvon, what i mean was hook a COMPUTER to the ethernet port and leave the DPR connected to the router wirelessly, this would allow you to speed test the connection between the DPR and the router.
NOT the PC to the printer.
Also NICE find, that'll do it every time.
