Unimplemented: opx.printer #340
Comments
I wonder if it would help to stub this out? |
Were there many third-party OPL apps that supported printing? A few banking apps maybe? |
Good question. I've no clue at this point. I'm currently stuck in the middle of a refactor of the software index importer, but as soon as I've done that I'm going to start pulling out information about which OPXs are used, etc. |
I think this is the first one I've come across, and printers weren't that common hooked up to Psions in the first place I don't think.
I stubbed out |
You know, if we've got no printing to reset, it sounds a lot like you've fully implemented |
Well, Psions came with Canon Bubblejet, HP Deskjet and LaserJet drivers and there were third-party PCL and Postscript drivers so that made quite a lot of printers compatible. And later came PDFPrinter to print as PDF. And printing was also possible via PC (PsiWin / plptools). |
PDFPrinter would be interesting as on iOS we could actually use that to bring up a print screen. @kapfab Do you remember how the PDF stuff actually worked under the hood and how the platform provided support for it (assuming it did)? |
It was a specific printer driver developed by the same author as PDF+, he reimplemented the whole PDF generation stack, translating the printing instructions into a PDF, directly on the Psion. |
Yeah. That makes sense. I imagine we'd have to do something from scratch if we went that way. Oh well, not for today, that's for sure. 🙃 |

Print operations are unlikely to ever be supported, unless someone wants to send me a working psion5 compatible printer to test with...
