    My old HP OfficeJet Pro K8600 wide format printer

    Fingers crossed that you find a satisfactory option. What was the last PC OS that gave you full functionality? Given that the K8600 was introduced in about 2007 I am quite amazed it has worked until just recently for you. Finding ink for an old model seems pretty amazing too given new models...

    Canon Pro-100 Took a tumble and now I cannot get it working properly

    Just as an FYI, neither of the links give public access and Google Drive wants one to Request Access. Fewer people will want to go through that process is my bet - FYI

    Canon Pro-100 Took a tumble and now I cannot get it working properly

    Hi @samboy Some volunteer during the week, some volunteer during the weekend, and some volunteer all week. Clearly, it's a frustrating situation. I hope you don't take this the wrong way, yet there is a parallel between your printer taking a tumble and trying to fix it over a forum and a...

    Canon Pro-100 Took a tumble and now I cannot get it working properly

    Here is a link to a prior post on the same error code: https://www.printerknowledge.com/threads/canon-pixma-pro-1-error-6010.10606/ Given it took a tumble, could be a lot of different things yet I hope list in the post helps narrow down where to look John Wheeler

    about reset epson l3250 printer

    Hi @raztech Printers have many reset options such as for scanning , network, etc. It would help if you provided more details of the problems you are having or trying to solve. If you are trying to do a product check, here are the steps and if should get to the point where it prints a nozzle...

    ArgyllCMS and X-Rite i1Pro2 target sets

    That's a good question that might not yield to a good answer without an experiment with target sheets done both ways. I did find out that I could see a visual difference when printing an image in 16-bit presented to the printer vs the same image in 8-bit presented to the printer...

    Thanks!! You desire an appropriate award (and yes I know you are on Windows rather than Unix Mac yet still a wizard)

    Same target: scanned by both Colormunki and i1Pro2, differences in profile quality ?

    Thank you for sharing the results of your experiments. It was excellent (and surprising) how closely the two profiles from two different instruments matched. I, too, have an Epson P900, yet I'm using all Epson inks. I am not the expert so admit I have a lot to learn. My understanding of the...

    Another Canon Pixma iP8750 problem

    @The Hat already gave you the best advice in using the official Canon printer driver and not to use AirPrint. I would start there. I don't have your printer yet, but several issues have been reported. I would only use the recommended software for printing CD/DVDs on your printer i.e. Canon...

    Another Canon Pixma iP8750 problem

    hi @sbelt Since you asked for "views" : If the problem is not resolved with the prior posted steps, it would be great to know if you had any issues when printing with the DVD/CD print tray, e.g., a print head strike or jam. Damage or contamination to the guide rails (upon which the print...

    Grey in nozzle check where it should be cyan!

    Great advice and observation by @PeterBJ When some problem appears and then disappears without a full explanation .i.e. intermittent, they often have the characteristic of returning in some fashion. Thank you for providing the PNG image of the nozzle check. A couple things still show some...

    Grey in nozzle check where it should be cyan!

    Hi John To get the best analysis of that nozzle check print, the best result is where the scan is of a clean nozzle check without a secondary nozzle check printed on the backside of the paper. Also, if you could do it in PNG format, it would be pretty helpful as JPEG artifacts interfere with a...

    HL-4570CDW Diagnostic Question

    Hi @jccorbi That is quite an investment of time and money to pump life back into that printer. Don' forget to consider having a replacement printer. Yes, you could look at the fuser as well. Note that I am no expert on laser printers, yet I have experience debugging several types of systems...

    8 vs 16-bit printer drivers and 8 vs 16-bit workflows

    No need for apologies @Tony4597, and thanks for the extra pointers. I participated in the offshoot as well. :) I have ignored the "Send 16-bit Data" checkbox for decades, so it was worth revisiting. I don't use a 16-bit workflow if not warranted and am only religious about making sure I have...

    Any Forum Member with Experience "Qimage One" for Mac

    Interesting discussion about 8 vs 16-bit printer drivers and 8 vs 16-bit workflows. As for me, with some experimentation, I did learn what the "Send 16-bit Data" option does and does not do, so that was worth the effort. Yet, since I started this thread about questions on Qimage One (of which I...

    8 vs 16-bit printer drivers and 8 vs 16-bit workflows

    That's a good question and I have some information to share yet it is only on a Mac system printing to an Epson P900 printer using the Epson Printer Driver (not the Apple version). I printed a detailed 16-bit computer-generated 3D image via ray tracing with all sorts of reflections and partial...

    Hi @Tony4597, it's been a while, and yes, I am the John Wheeler posted on ReTouchpro. I still do on some of the other Photoshop forums. I'm glad to meet you again. Thanks for your experience with Qimage for Windows. I am a bit (OK, a lot) jealous of that, as its features are pretty enticing...

    Hi @GordW Thanks for sharing your experience. I did sign up for the 14-day trial. In parallel, I am focusing on the Epson driver, so I know what it offers when I compare it to Qimage One. I had to reinstall the Epson drivers and then got caught in the Black Hole of Apple's version of Epson's...
