USB (DOT4) Printers & OS4.1 **Testing in Progress**

Not really, the point of the software shutdown is to make everything do a save before the power goes, I would suggest that what needs to happen is that a trigger to save everything needs to happen, it's unlikely to be effective until apps get updated, but one way of doing it would be to get running apps to "register" with application.library (in a similar way as was described for screensaver triggering etc), with a "save current status" function that would get called by the application.library when the apcupsd triggered it.

You would have the benefit of still being able to just turn off in this case, but would rely on application programmers to register this.

Yes and isn't it what an UPS driver is supposed to do ? Also I can't see an UPS driver until you have a software shutdown else there is no point in it (except for postponing a few minutes the power outage

but these don't work with DOT4 printers via USB & that's why we need rwo's driver

The USB Printer protocol, the normal or ieee1284.4 is only a way to transport data.

So the driver do not care if the Printer is a PostScript / PCL / plain ASCII driver or some custom setup, it just takes data and send it over usb too the printer.

about my current progress. I have been redesigning the DOT4 work flow and recoded at lot of subfunctions, this is too make a flexiable dot4 driver. Some of the log reports I got back showed some problems.

I hope too have a new test driver up and running soon.

@rwo

great news & big thanks ..hoping I can get at least basic text to print on my LaserJet 1012 & I will be very happy

I wrote the dot4 code.

I added some code to retieve more data if you run out, but this code is unused as my printer do not use this.

could you please test the new version for me.

@rwo

big thanks for the update! its getting better as I don;t get an immediate guru and system hang up but I cannot print using postscript as I only get the followung line in both DOpus and AmiPDF

"%!PS-Adobe-3.0
%%Document Meida: letter 612 792 0 () ()
%%EndComments
The line abo"
now when i change to generic I get the first 5 or 6 lines printed in DOpus of the help file but nothing from AmiPDF?? tried turning the printer on/off but same problems...

I have sent you the dot4.txt file in RAM....I feel a full page printing soon..thanks again for tackling this important driver for us

edit: oh again I'm using a HP LaerJet 1012

Hmm I looked at the log you send me, the driver has not reistred any data too send, weird.

The driver also sends out debug output too serial, I would like too have that too, if you could send me that.

If you don't have another computer to capture that, you can use the c:DumpDebugBuffer too retrieve the data.

I think you just have to do a c:DumpDebugBuffer ram:dot4.serialtxt

@328gts

forgot to say thanks for the log.

@Chris

Also thanks for the log, I can see the printer send me one or two commands that I have not implemented yet.

To know which one, I also need the serial output from this driver.

RWO

@rwo
ok dot4.serial.txt sent off to ya mate

@328gts

I looked at the Logs you send me, and the driver never recives any data too print.

so next time you try and print any thing only use Multiview or a shell

in the shell you can just do this 'echo "123" >prt:'

if that works we have to look at what you are doing since it fails.

@328gts
Printing from AmiPDF etc. is a bad idea for testing... to many things can go wrong.... the given lines above will also be printed if the page margins donot fit the printerpaper e.g. I use a Xerox 6180MFP Postscript and most of the time setting bigger margins helps... So, yes for testing purposes the shell is the way to go (as rwo suggested).

KEEP UP THE GOOD WORK RWO !!!

@rwo

ok tried the echo command and it works fine! however, in MultiView I tried prinitng out a txt file and only the first 3 lines of the first page were printed and I get a pop upm screen saying "printer trouble-out of paper"

sent you the dot4.txt and serial.txt files

@gerograph

thanks for the tips..i'll give them a try

@rwo

Just capturing the serial for you now

@rwo

Will this driver work with my hp deskjet 5550 usb printer? Anyone know or tried?

Hi,

I know this is a SamFlex topic, but...

Will this driver work with my Q5987A - HP Color LaserJet 3600n usb printer on my uA1 running AOS ver 4.1?

See https://h10057.www1.hp.com/ecomcat/hpc ... provisioner/99/Q5987A.htm

For printer info.

Anyone know or tried?

I'm a real Noob to printing on my uA1 and really dont want to try "anything" which may cause damage to it.

@Antique

Hp deskjet 5550 works with the echo "123" >prt: :)

@rwo

any new news

@328gts

I uploaded another version, I hope this version works better.
