I have a HP 1018, which was an XP only printer when bought ( there weren`t even Mac drivers at the time ).

From the HPLIP page for the specific model :
Quote:

A driver plug-in is required . Driver plug-ins are released under a proprietary (non-open) license and are not part of the HPLIP tarball release.

Chances are rather dim for AOS4 printing...

hemm...
Was this not ported a long time ago?

Thats what I say all the time... there are more HP (and Epson and Canon and...) printer models supported by a proprietary "plug in" (or whatever they call it) only.

For HP, all printer models supporting resolutions > 600 DPI are "supported" this way (PCL3GUI, LIDIL, GDI etc.). So there is still very little chance that there is support for "modern" printer models in long term.

I think that it is much more work to develop a framework for the Linux PPC drivers (which are able to make use of some, but not all!, "driver plug-ins") than to do a suitable PostScript or PCL5/6 driver for the current printing system and live with the fact, that those printers cost a bit more than the "consumer" models, which are cheap to buy, but quite expensive to run for some time.

I don't see printing an issue any more, largly thanks to these email printers, where you just have your printer connected to the net and then email the doc to it and its print away, this was developed so that device without drivers like Smartphone and tablets can use the printer but it also befits our community. Both hp and Epson offer printers that can do this.

Looks promising thanks for your efforts.

If all is open source, why should e.g. HP ask for a fee, so that an interested developer could see the informations regarding e.g. a PCL3GUI capable driver?

This shouldn't be a problem. At the time I compiled the first version of the HP_Photosmart driver I searched on the HP site IIRC and was able to download a document with the PCL3GUI commands and escape codes. Either HP or Google. Unless things have changed the infomation should be freely available.

Of course instructions for coding are different to source code performing the coding itself but it's better than being in the dark.

FWIW I found info on RGB mode and PCL3GUI commands. But I can't find any PDF with it on my system!

@Trixie

I doubt that. The annoying bug where you can't run a program scanning the device list (such as Media Toolbox) without getting 15 requesters about your printer not being connected must be over two years old now! And it has no sign of being fixed. I don't think OS4 developers use printers, they use serial interfaces and debug terminals.

Does this happen also if you adjust the Threshold to be lighter?

PCL3 is a well-known standard that the majority of printers support. Actually the majority support PCL5, but that implies support for PCL3 (AFAIK). Anything that doesn't support PCL will usually support PostScript. We don't actually have that much of a problem with drivers - the majority of sane printers will work with the HP_LaserJet_4 or the PostScript driver.

Inkjets are more troublesome than lasers, because they tend to be built as cheaply as possible.

My biggest bug-bear with OS4 printer support is the remaining lack of a Dot4 compatible usbprinter.device. RWO's half-completed one on OS4Depot never worked properly for me, and no manner of printer drivers will encourage OS4 to communicate with a printer that only supports a protocol it doesn't understand.

Excellent!

It's good if PCL can support a variety of printers. Then we just need a generic PCL driver. What we do need is an auto printer selector like in Linux where it detects the printer and sets up the driver for you.

Canon used to be supported but do these use PCL? We had some Epsom drivers but trying to use an Epsom printer can just result in the printer ignoring you. I read some command code it needs before it works.

See, all these printers have these quirks. So even if they all spoke PCL it is useless if they don't accept it by default. It may be only a few characters in some init string but without it there it makes all the difference.

I can't speak much for Dot4 myself. What printers use it? What features can it give us?

As long as there is support for common garden variety printers (HP, Canon, Epsom ink jet) the main groundwork is covered and then we can dig deeper into more advanced features later I think.

Quite a few, actually.
