I am attempting to write a 1.3 printer driver for a CItoh ProWriter
using Manx C and am having a number of problems. (No Laughing, Please).
I believe that I am having problems when the driver functions are being
called, but not sure.
I purchased the 1.3 developer's update from Commodore, but I'm a little
lost and sure could use some help.
1) Is there a 1.3 compatible ProWriter driver out there that supports
more than the lowest resolution? (Ok, so I'm lazy)
2) Is my problem that I am using Manx C?
3) Is there any source code that is close which I could look at (Manx),
because I really would like to figure this thing out.
Again, I have purchased the copyrighted stuff from Commodore, so no
need to duplicate that. Just would like to to get a little better
resolution out of my ProWriter.
Thanks,

This driver does graphics dumps even under 1.3 with NO problems ... it doesn't do italics, but the printer itself doesn't have a built-in italic character set. I don't understand Kent's: "Is there a 1.3 compatible ProWriter driver out there that supports more than the lowest resolution?" When in "binary bit map" mode, the printer has but one resolution, so I don't see how the "DENSITY" (in Preferences Graphic Screen 2) is relevant. Kent continues: "Is there any source code that is close which I could look at (Manx), because I really would like to figure this thing out." How would you like it?

As someone mentioned in a response, I'd get an updated printer, but this thing won't wear out & I can't justify one until it does :^) >What I've been using for QUITE some time is: > >----ar-e- 87-04-05 21:47:29 7 3248 PROWRITER Mine - circa 8-86: CItohProwriter ---ar-e- 3292 7 24-May-89 18:28:58 >[...] This driver does graphics >dumps even under 1.3 with NO problems ... it doesn't do italics, but the >printer itself doesn't have a built-in italic character set. Mine works under 1.3, but never did graphics very good. Takes two passes to complete a line & thus leaves a vertical trail about 3/4th's the way across the page where the second pass occured. >> [...]that supports more than the lowest resolution?" > >When in "binary bit map" mode, the printer has but one resolution, so I don't >see how the "DENSITY" (in Preferences Graphic Screen 2) is relevant. Mine has four resolutions when in "Bit Image Graphics" mode: Pitch Dots Per Inch Dots Per Line 10 CPI (Pics) 80 640 12 CPI (Elite) 96 786 17 CPI (Compressed print) 136 1088 Proportional Spacing 160 1280 (from p.3-43 Users Manual) Graphics resolution is set by changing the print pitch. Last year someone posted a prowriter driver which he said supported 3 densities, so i downloaded it. Unfortunately, it was exactly the same file as mine (checked it 3 times to make sure I wasn't screwing up), so I figure he sent the wrong one. Unfortunately, I could not reach him to inform him of the mistake and never pursued the problem since I didn't use graphics much with this printer. Well my wife has taken an attraction to ProWrite & I sure wish I could get decent output at a higher density from it now.
