Other than magnifying the perfectly readable pc image before printing off on
laser printer,is there any other way of getting a printed image to be as
(almost) clear as the PC screen image ?
Say a schematic original is 4 A4 sheets then scanned in 1 to 1 (about, so to
allow some overlap) , in 4 sections, it needs printing off on 16 sheets to
get anywhere near to the original in resolution. Assuming a decent GIF image
rather than the usual joke PDF, better-than-nothing, stuff.

Update on previous thread on copying old brown paper schematics, the simple
way to increase the contrast was to scan in and just select "reduce colour
depth" in viewer, to just 2 colours and save as .gif , but then comes the
usual printing off problem.

I've had the same issue. I download schematics in PDF and try to follow
the circuit by magnifying and scrolling. It's pretty daunting. I've
compensated somewhat by having a PC with a good monitor right at the
workbench. It seems as if I don't have enough hands to scroll the
diagram while simultaneously tracing the physical circuit on the device
itself.

I suspect that it is an acquired skill.

If you have something like a Kinko's (full service copying/printing
business graphics facility...they're everywhere here in the States)
across the Pond, you can have full-sized (or larger) paper prints made
of your PDF's.

I'm gonna try this as a stopgap while I practice doing it electronically.
