RetroPrinter Support

I've put the retro printer aside for a bit while I tested a different approach.

One thing that popped up during testing was to get a successful print, things needed to be powered up in a specific order.
If powered up out of sequence, the pi would not print the data sent from my controller, but ...

Just wondering if you've had chance to test the printer yet.
I'd really like to get this working with passthrough. Converting to PDF works well but is too slow for my needs. Our controllers push printouts faster than the PI can process the info.

Thanks again
Cory.

I've tested on a win xp machine with data_bit 7 and 8.
7 gives a raw file but 8 didn't.

Neither produced a print.

I plugged my printer into a usb on the xp machine and loaded various laserjet drivers, and printed a test page using pcl5, pcl6 and postscript.
I also loaded a inkjet driver and sent ...

Thanks.

The laserjet m404dn supports HP PCL 6, HP postscript level 3 emulation, PDF, URF, PWG Raster
I'll drag out some other hardware and test with PCL 5, I may get different results.

Thanks for looking into this.

I'll have to recreate the scenario that pushed out the raw file and send it over with another photo.

The manual shows to set the emulation to HP for passthrough. I have the option to push ASCII, epson, and others.... if these will simplify things?

Thanks for looking into this.

I changed the bit depth but made no difference.
I'm about to send you a raw file from today's test.

Thanks

Thank you.
I'll send some over when I get back to the office.

I have also tried a Samsung printer, the latest retro printer software, sending print jobs from a pc, albeit with a usb to centronics adapter, and various drivers but the outcome is the same.

I've set the output_printer to yes and run suggested commands again and managed to get the attached image to print, although the information is jiberish, it may be relevant to my issue?

I've been at it again this morning.

I can verify I have a default printer using "lpstat -d" and I can print the txt files sent from our controllers using "lp filename.txt"
I can see a raw file enter the folder after my controller send a print job and I can open it and looks as expected. It just won ...

With the suggested commands, it looks to be writing the raw file ok.

No more data received from centronics port
write /tmp/24.raw
4 sec over
command = cp /tmp/24.raw /home/pi/data/raw/24.raw
No more data received from centronics port
4 sec over

I dont see any errors.

Forgot to mention I'm on v3 ...
